Previous commit split _check_ffmpeg into a side-effect-free
_locate_ffmpeg + the original auto-download _check_ffmpeg, and moved
__init__ to call _locate_ffmpeg. That alone wasn't enough — caught
the gap during a deeper audit:
is_configured() → is_available() → _check_ffmpeg() (with download)
The orchestrator registry, download engine, and the orchestrator's
own configured_clients() all probe is_configured() polymorphically at
boot. So when tests import web_server, the registry probes
youtube.is_configured() → is_available() → _check_ffmpeg() →
DOWNLOAD. My __init__ change didn't help because the registry boot
fires the same code path right after.
Real fix: gate the download branch inside _check_ffmpeg itself.
Returns False (and logs a warning) when running under pytest or when
SOULSYNC_NO_FFMPEG_DOWNLOAD=1. End users on a fresh install still get
auto-download on first real YouTube use (gate is off in production).
Container is unaffected (system ffmpeg via apt is found on PATH, the
download branch never runs).
Three detection paths in _auto_download_disabled():
- SOULSYNC_NO_FFMPEG_DOWNLOAD env var (explicit opt-out for CI /
build steps that want to disable outside pytest)
- PYTEST_CURRENT_TEST env var (set by pytest per-test — covers
in-test-body call path)
- 'pytest' in sys.modules (covers calls fired during pytest collection
/ import phase, BEFORE the per-test env var is set — which is
exactly when registry.py probes is_configured() at web_server
import time)
Verified by inspecting tools/ after a full suite run — empty (was
~388 MB after a single test_tidal_auth_instructions.py run before
the gate). Container behavior unchanged: shutil.which('ffmpeg')
returns /usr/bin/ffmpeg from the apt-installed package, so the
download branch is never reached anyway.
5 new pinning tests:
- pytest-in-sys.modules detection works
- PYTEST_CURRENT_TEST env detection works
- SOULSYNC_NO_FFMPEG_DOWNLOAD env detection works
- _check_ffmpeg returns False (no urlretrieve, no tools/ dir created)
when gate is on and ffmpeg is missing — pinned by trapping
urlretrieve to AssertionError so a regression blows up loud
- _locate_ffmpeg never triggers download or creates tools/ —
pinned by trapping both urlretrieve AND Path.mkdir on tools-prefixed
paths

kettui reported the dev image roughly doubled in size after a recent
nightly build. codex investigation traced it back to:
1. nightly workflow runs `python -m pytest` before docker build
2. one of the new tests imports web_server (test_tidal_auth_instructions.py)
3. importing web_server constructs YouTubeClient
4. YouTubeClient.__init__ called _check_ffmpeg() — which auto-downloads
a ~388 MB ffmpeg/ffprobe bundle into ./tools/ when system ffmpeg
isn't on PATH (CI runner doesn't have it)
5. .dockerignore didn't exclude tools/ffmpeg or tools/ffprobe
6. docker `COPY . .` shipped the binaries
7. the immediately-following `chown -R /app` rewrote every file into
a new layer — so the 388 MB payload got counted twice in image
size
three fixes:
1. .dockerignore — block the auto-downloaded binaries even if they
leak into the workspace (tools/ffmpeg, tools/ffprobe, .exe variants,
.zip and .tar.xz download archives). Defense-in-depth so a future
regression in the test/import path can't bloat the image again.
2. youtube_client — split _check_ffmpeg into a side-effect-free
_locate_ffmpeg (pure existence check) and the original auto-
download _check_ffmpeg. __init__ now calls _locate_ffmpeg + logs
a warning when missing instead of triggering download. is_available()
and the actual download dispatch paths still call _check_ffmpeg —
so end users still get auto-download on first YouTube use, but
`import web_server` doesn't drag a 388 MB binary into the workspace.
3. Dockerfile — replaced `COPY . .` + `chown -R /app` with
`COPY --chown=soulsync:soulsync . .` + a scoped chown on just the
runtime mount-point dirs. eliminates the layer that duplicated
the entire /app tree just to flip ownership bits, so even legit
workspace content isn't double-counted in the image.
Combined effect: image size returns to baseline + future ffmpeg leaks
can't bloat it. Inside the container nothing changes — the Dockerfile
already installs system ffmpeg via apt, so YouTube downloads find it
on PATH on first use and the auto-download path never fires.
2259 passed, 1 skipped, 0 failed.
Three follow-on fixes to the manual-search candidates modal once people
started actually using it:
1. NDJSON streaming. Manual search waited for every source to return
before showing anything. Now streams one event per source as each
completes — header line, source_results per source, done terminator.
Frontend appends rows incrementally via response.body.getReader().
2. Manual picks no longer auto-retry on failure. New _user_manual_pick
flag set on the task in /download-candidate. Both monitor retry
paths (not-in-live-transfers stuck + Errored state) bail on the
flag. Surfaces the failure to the user instead of silently picking
a different candidate via fresh search.
3. Non-Soulseek manual picks (youtube/tidal/qobuz/hifi/deezer/
soundcloud/lidarr) no longer stuck at "downloading 0%" forever. The
live_transfers IF branch now marks manual-pick tasks failed
directly when the engine reports Errored, instead of deferring to
the monitor (which bails on manual picks). Engine fallback in else
branch covers the rare race where the orchestrator's pre-populated
transfer lookup is missing the entry.
Plus a deadlock fix discovered along the way: the new failure path
synchronously called on_download_completed while holding tasks_lock,
which itself re-acquires the same Lock — non-reentrant
threading.Lock self-deadlocked the polling thread. While wedged, every
other endpoint that needed the lock (including /candidates → other
failed rows couldn't open modals) hung waiting. Moved completion
callbacks onto a daemon thread so the lock releases first.
Plus failed/not_found/cancelled rows are now ALWAYS clickable (not
just when the auto-search cached candidates) — the modal carries the
manual search bar, which is the user's recourse for empty results.
Plus manual download worker now runs on a dedicated thread instead of
competing with the batch's 3-worker missing_download_executor pool —
saturated batches no longer queue manual picks indefinitely.
All scoped to manual picks via the _user_manual_pick flag — auto
attempt flow byte-identical to before. Engine fallback gated on the
flag too so auto attempts in the else branch keep the original
do-nothing behavior (safety valve handles the stuck-forever case).
Also dropped _handle_failed_download from web_server.py — defined
but had no callers (dead code).
17 new unit tests pin the gate behavior:
- engine fallback: Errored/Cancelled/Succeeded/InProgress transitions,
manual-pick gate, terminal-state skip, soulseek skip, missing
download_id skip, engine returning None, orchestrator exception
- monitor: manual-pick skips not-in-live-transfers retry + Errored
retry
- IF-branch end-to-end: Errored marks failed, "Completed, Errored"
hits failure branch, auto attempts defer to monitor
Manual-search endpoint tests rewritten for NDJSON: 11 cases (validation,
single-source dispatch, parallel "all" dispatch, one-event-per-source
streaming shape, unconfigured-source skip + reject, header metadata,
per-source exception isolation).
Full suite 2259 passed, 1 skipped.
Four selection-quality fixes on the SoulSync-made discover playlists.
None change public method signatures; all are tightenings on what's
already there.
(1) Diversity for Hidden Gems + Discovery Shuffle
Both used to be `RANDOM() LIMIT N` with no diversity. Could return
50 tracks from one artist or 20 from one album if the discovery
pool happened to be skewed. Both now over-fetch 3x and run the
existing `_apply_diversity_filter`:
- Hidden Gems: max 2 per album, 3 per artist
- Discovery Shuffle: max 2 per album, 2 per artist (tighter — shuffle
should feel maximally varied)
(2) Source-aware popularity thresholds
`popularity >= 60` for "Popular Picks" and `popularity < 40` for
"Hidden Gems" was Spotify-shaped (0-100 scale). Deezer writes its
`rank` value into that column (often six-digit integers); iTunes
writes nothing meaningful. For Deezer-primary users:
- Popular Picks pulled essentially everything (rank >= 60 = all)
- Hidden Gems pulled essentially nothing (rank < 40 = none)
New `_get_popularity_thresholds(source)` helper returns per-source
values:
- Spotify: (60, 40) — the existing 0-100 scale
- Deezer: (500_000, 100_000) — ballpark from real rank values
- iTunes / unknown: (None, None) — skip the popularity filter
entirely, fall back to random + diversity
`get_popular_picks` and `get_hidden_gems` now consult the helper.
When threshold is None they skip the popularity SQL filter. Diversity
+ ID gate still apply.
(3) Push genre keyword filter into SQL
`get_genre_playlist` used to fetch `limit=1_000_000` rows into Python
then run a substring keyword filter on `artist_genres`. Bad on big
discovery pools.
Now the keyword OR chain is generated as SQL placeholders:
AND (artist_genres LIKE ? OR artist_genres LIKE ? OR ...)
Each placeholder gets `f'%{keyword.lower()}%'` via `extra_params`.
`fetch_limit` drops back to `limit * 10`. `_genre_matches` Python
helper deleted (only intra-file caller; verified via grep).
Parent-genre expansion via `GENRE_MAPPING` preserved — keywords list
feeds the LIKE chain unchanged.
(4) Filter out tracks already in library
Discovery pool can include tracks the user already owns. Hidden Gems
/ Shuffle / Popular Picks shouldn't surface those.
`_select_discovery_tracks` gained `exclude_owned: bool = True`
parameter. When True, adds a correlated NOT EXISTS subquery against
the `tracks` table covering all 3 source IDs:
AND NOT EXISTS (
SELECT 1 FROM tracks t WHERE
(t.spotify_track_id IS NOT NULL AND t.spotify_track_id = discovery_pool.spotify_track_id)
OR (t.itunes_track_id IS NOT NULL AND t.itunes_track_id = discovery_pool.itunes_track_id)
OR (t.deezer_id IS NOT NULL AND t.deezer_id = discovery_pool.deezer_track_id)
)
Note column-name asymmetry: tracks.deezer_id vs
discovery_pool.deezer_track_id. Inline comment marks the trap. All
5 public discovery methods automatically benefit (default True).
Seasonal Playlist doesn't go through the helper so it's unaffected
(curated content, dedup is wrong intent there).
Tests
12 new tests in `tests/test_personalized_playlists_id_gate.py` (27
total in the file):
- Hidden Gems + Discovery Shuffle apply diversity (cap proven by
inserting 10 same-artist + same-album rows and asserting return
count ≤ per-album cap)
- Popularity thresholds: Spotify (60, 40), Deezer larger scale,
iTunes None / None
- Popular Picks skips threshold filter when None
- Genre playlist pushes filter to SQL (parent + child genre expansion)
- Owned-track exclusion: filtered when match, kept when no match,
opt-out flag works
- Deezer column-name asymmetry pinned (regression footgun)
Test fixture re-added the minimal `tracks` table (4 columns: id,
spotify_track_id, itunes_track_id, deezer_id) — only what the new
NOT EXISTS subquery needs to join. Plus `insert_library_track`
helper.
Verification
- 27/27 in this test file pass (15 prior + 12 new)
- 2232/2232 full suite green
- ruff clean
LOC delta:
- core/personalized_playlists.py: 1030 → 1101 (+71)
- tests/test_personalized_playlists_id_gate.py: 352 → 616 (+264)
The original gate baked into `_select_discovery_tracks` only checked
Spotify + iTunes:
AND (spotify_track_id IS NOT NULL OR itunes_track_id IS NOT NULL)
For Deezer-primary users, discovery_pool rows have populated
`deezer_track_id` but NULL Spotify + NULL iTunes IDs. The gate
filtered every row out — Time Machine, Genre Browser, Hidden Gems,
Discovery Shuffle, Popular Picks all rendered "no tracks found" for
every tab on every Deezer-primary install.
Extended the gate to include `deezer_track_id` and added that column
to the standard SELECT column tuple. `_build_track_dict` already
exposed `deezer_track_id` in its output shape, so frontend rendering
needed no changes.
Regression pinned via new test
`test_discovery_helper_accepts_deezer_only_id_rows` — inserts a row
with NULL Spotify + NULL iTunes but a populated `deezer_track_id`
and asserts it survives the gate.
2220/2220 full suite green.
Owner decision: not worth shipping. The four library-driven personalized
sections were stubbed returning [] for ages because their schema
prereqs didn't exist; the prior commit re-enabled them by routing
through a new `_select_library_tracks` helper. Owner reviewed and chose
to delete the sections entirely instead.
Removed everywhere:
- `core/personalized_playlists.py` — `get_recently_added`,
`get_top_tracks`, `get_forgotten_favorites`, `get_familiar_favorites`
+ the `_select_library_tracks` helper (no other callers; verified
via grep).
- `web_server.py` — 4 route handlers
(`/api/discover/personalized/recently-added`, `top-tracks`,
`forgotten-favorites`, `familiar-favorites`).
- `webui/index.html` — 4 `<div class="discover-section">` blocks
(`#personalized-recently-added`, `#personalized-top-tracks`,
`#personalized-forgotten-favorites`,
`#personalized-familiar-favorites`).
- `webui/static/discover.js` — 4 load functions
(`loadPersonalizedRecentlyAdded`, `loadPersonalizedTopTracks`,
`loadPersonalizedForgottenFavorites`, `loadFamiliarFavorites`),
plus their entries in `loadDiscoverPage`'s Promise.all, plus
4 module-level state vars + 6 dead branches across
`openDownloadModalForDiscoverPlaylist` / `startDiscoverPlaylistSync`
and the sync-progress / rehydrate dispatchers.
- `webui/static/helper.js` — 4 tooltip / docs entries.
- `webui/static/sync-spotify.js` — 1 stale rehydrate dispatcher
branch (`discover_familiar_favorites`) caught during the global
grep pass.
- `tests/test_personalized_playlists_id_gate.py` — 3 library-method
tests + the test infrastructure that supported them
(`tracks` schema, `insert_library_track` helper). Documentation
header updated to reflect the deletion.
Net: -527 / +2 lines across 7 files.
What stays:
- Daily Mixes (also in personalized package, intentionally paused —
separate decision).
- Popular Picks + Hidden Gems + Discovery Shuffle (alive, not
affected by this deletion).
- All 14 tests in the personalized-playlists test file still pass.
- The PersonalizedPlaylistsService lift from the prior commit
(`_select_discovery_tracks` etc) — those are still in active use
by the surviving discovery_pool methods.
DISCOVER_TRACK_SELECTION_REVIEW.md at repo root contains historical
references to the four deleted endpoints. Treated as historical
context (same policy as WHATS_NEW), left alone.
2219/2219 full suite green (was 2222 - 3 deleted tests = 2219).
JS parses clean, ruff clean.
User-facing bug found in the discover-page audit: multiple sections
(hidden gems, discovery shuffle, popular picks, decade browser,
genre browser) had no `WHERE (spotify_track_id IS NOT NULL OR
itunes_track_id IS NOT NULL ...)` gate. Tracks with no source IDs
in the discovery pool got displayed, the user clicked download, the
download silently failed because there was nothing to look up.
Lift + gate
`PersonalizedPlaylistsService` had 5 selection methods that all shared
the same shape — connect to DB, run a SELECT against `discovery_pool`
with different WHERE clauses, optionally apply diversity, return
list of track dicts. ~366 lines of business logic, ~55% of which was
repeated boilerplate.
Three new private helpers consolidate everything:
- `_select_discovery_tracks(*, source, extra_where, extra_params,
order_by, fetch_limit, extra_columns)` — shared SELECT against
`discovery_pool`. The mandatory ID gate is hard-coded into the
WHERE clause: no opt-out flag, every method inherits it for free.
Plus the source filter and the blacklist filter — same shape every
selector needs.
- `_apply_diversity_filter(tracks, *, max_per_album, max_per_artist,
limit)` — per-album / per-artist cap loop, returns trimmed list.
Lifted from the inline duplicates in decade / genre / popular_picks.
- `_compute_adaptive_diversity_limits(tracks, *, relaxed=False)` —
step-function tiers based on unique-artist count. `relaxed=True`
gives the slightly looser limits the genre playlist used vs the
decade playlist.
Re-enable 4 library methods
`get_recently_added`, `get_top_tracks`, `get_forgotten_favorites`,
`get_familiar_favorites` were all stubs (`return []`) because they
predated the schema columns they need. Schema now has them:
`tracks.created_at`, `tracks.play_count`, `tracks.last_played`, and
the source ID columns added in earlier work.
New `_select_library_tracks(*, where_clause, params, order_by, limit)`
helper mirrors the discovery selector but targets the `tracks` table
joined against `albums` + `artists`. Mandatory ID gate lives in the
helper too: every library method automatically rejects rows where
spotify_track_id, itunes_track_id, deezer_id,
musicbrainz_recording_id, AND audiodb_id are all NULL.
Selection rules:
- `get_recently_added` — ORDER BY created_at DESC
- `get_top_tracks` — WHERE play_count > 0 ORDER BY play_count DESC
- `get_forgotten_favorites` — WHERE play_count > 5 AND last_played
< (now - 90 days) ORDER BY play_count DESC
- `get_familiar_favorites` — WHERE play_count BETWEEN 3 AND 15
Tests
`tests/test_personalized_playlists_id_gate.py` — 17 tests pinning:
- `_select_discovery_tracks` filters NULL-id rows, honors source +
blacklist + extra_where
- `_apply_diversity_filter` caps per-album + per-artist + stops at
limit
- `_compute_adaptive_diversity_limits` returns the right tier for
unique-artist count + relaxed flag
- All 5 discovery methods (decade, popular_picks, hidden_gems,
discovery_shuffle, genre is exercised via the helper) reject
NULL-id rows
- All 4 library methods reject NULL-id rows + honor their
play-count rules
Behavior preserved
Same diversity tiers, same over-fetch multipliers (10x for decade /
genre, 3x for popular_picks), same `popularity DESC, RANDOM()`
ordering, same `popularity >= 60` / `< 40` thresholds, same
blacklist filter. Public method signatures unchanged — `web_server.py`
needs zero edits.
Net file: 1089 → ~1170 LOC (helpers + docstrings), but actual
business logic across the 9 methods went from ~418 lines down to
~195 (-53%).
2222/2222 full suite green (was 2205 + 17 new). Ruff clean.
Closes#513 (s66jones).
The artist detail page already showed a "Popular on Last.fm" sidebar —
list of an artist's top tracks by playcount, with a play button per row
but no download action. Issue #513 wanted a way to grab those tracks
the same way zotify let users grab "top X songs" without pulling the
full discography.
Pulls from the configured primary metadata source (Spotify
`artist_top_tracks`, Deezer `/artist/{id}/top`) when available, falls
back to the existing Last.fm display-only mode for sources that don't
expose popularity ranking (iTunes / Discogs / MusicBrainz). Source
label in the section title shifts to match.
Each row gets a hover-revealed download button that wishlists the
single track via the existing /api/add-album-to-wishlist endpoint
(preserves the track's real album metadata, so the wishlist worker
later places the file in its proper album folder).
A "Download All" footer button opens the standard download modal in
PLAYLIST context, not album context — the virtual playlist_id is
`top_tracks_<source>_<artistId>` which doesn't match any of the
album-prefix checks in `startMissingTracksProcess` (downloads.js).
That keeps `is_album_download=false`, so the master worker doesn't
inject a wrapper context as `_explicit_album_context`. Each track
downloads using its own real album metadata, files land in proper
per-album folders on disk (not a fake "Top Tracks" folder).
Backend additions:
- `SpotifyClient.get_artist_top_tracks(artist_id, country, limit)` —
wraps `spotipy.artist_top_tracks`, returns up to 10 tracks for the
market (Spotify's API cap). UI-side limit trim only.
- `DeezerClient.get_artist_top_tracks(artist_id, limit)` — wraps
`/artist/{id}/top?limit=N`, converts Deezer's raw shape to the same
Spotify-compatible dict layout (id, name, artists, album with
album_type / total_tracks / images, duration_ms, track_number,
disc_number) so downstream code doesn't branch on source.
- `GET /api/artist/<id>/top-tracks` — dispatches to whichever client
matches the primary source. Resolves per-source artist IDs from the
DB row first (matching what /discography already does) so a Spotify
ID in the URL still works when Deezer is primary, and vice versa.
Returns `{success, source, tracks, resolved_artist_id}` on hit;
`{success: False, reason: 'unsupported_source' | 'spotify_not_authenticated'
| 'deezer_unavailable' | 'no_tracks_found'}` on miss so the frontend
can decide whether to fall through to Last.fm.
Frontend:
- `_loadArtistTopTracks` tries the metadata source first, falls
through to the legacy `/api/artist/0/lastfm-top-tracks` call if the
source can't deliver. Section title and per-row UI shift based on
which source answered.
- New per-row `.hero-top-track-download` button (hover-revealed).
- New `.hero-top-tracks-download-all` footer button — only visible
when metadata-source mode rendered the list (Last.fm fallback hides
it since rows have no track IDs to download).
Tests: 10 new tests pin the client methods —
- Spotify: returns track list, honors UI limit cap, returns empty when
unauthed / artist_id missing / API throws.
- Deezer: shape conversion to Spotify-compatible dict, empty when no
data / artist_id missing, limit clamping at upper bound, default
fallback when limit=0, malformed entries skipped.
The Flask endpoint dispatcher itself isn't covered by the new test
file because importing web_server at test-collection time spins up
worker threads that race with caplog-using tests elsewhere in the
suite (specifically test_library_reorganize_orchestrator). Endpoint
verified manually; the underlying client methods (the load-bearing
logic) are covered.
2204/2204 full suite green (was 2194 + 10 new).
Discord report (corruption [BWC]): downloads coming through as the
instrumental cut when a vocal track was requested. The verification
step's `_normalize` function strips parentheticals and version-suffix
tags ("(Instrumental)", "- Live", etc) so legitimate name variations
don't false-fail the title-similarity check. That also means "In My
Feelings" and "In My Feelings (Instrumental)" both normalize to "in
my feelings", title similarity is 1.0, and the wrong cut passes
verification.
Detect the version label on each side BEFORE normalization runs. If
the expected and matched recordings disagree on version (one is
original, the other is instrumental / live / acoustic / remix /
etc), return FAIL — the fingerprint identified a real song, just
not the version the caller asked for.
Reuses `MusicMatchingEngine.detect_version_type` so the same regex
patterns the pre-download Soulseek matcher applies also drive
post-download verification. No duplicated tables.
Also gates the secondary fallback scan, so a wrong-version variant
sitting in the same fingerprint cluster can't win the loop after
the best match has already been version-rejected.
6 tests pin the behavior:
- instrumental returned for vocal request → FAIL
- vocal returned for instrumental request → FAIL
- live vs acoustic → FAIL
- matching versions on both sides → PASS
- original-to-original happy path → PASS (regression guard)
- secondary scan skips wrong-version recordings → not PASS

Catches the silent excepts the awk-based earlier sweeps missed:
- Bare `except:` followed by `pass` (also swallows KeyboardInterrupt
and SystemExit — actively wrong). Upgraded to `except Exception as
e: logger.debug("...: %s", e)`. ~14 sites across connection_detect,
soulseek_client, listenbrainz_manager, watchlist_scanner,
youtube_client, navidrome_client, jellyfin_client, web_server.
- `except Exception:` + pass that the awk pattern missed (e.g.
multi-line or unusual whitespace). ~31 sites across automation_engine,
database_update_worker, music_database, spotify_client, web_server,
others.
- 14 legitimate cleanup sites left silent with explicit `# noqa: S110`
+ comment explaining why (atexit handlers, finally-block conn.close
calls). Logging during shutdown can itself crash because file handles
get torn down before the handler fires.
Also enables `S110` rule in pyproject.toml so this pattern fails CI
going forward — drift fails at PR review instead of at runtime against
a wedged worker thread. Tests path keeps S110 ignored (test fixtures
legitimately use try-except-pass for cleanup).

Refs #369
Discord report: Duplicate Detector card said "372 findings" and Cover
Art Filler said "60 findings", but clicking the Findings tab's Pending
filter showed 0. User read it as "findings aren't being created" —
looked like a detector bug.
Actual cause: the badge sourced ``last_run.findings_created``
(historical "found in last scan") without considering current state.
After the user (or bulk-fix automation) resolved or dismissed those
findings, they no longer appeared on the Pending tab — but the badge
kept showing the last-scan number in red urgent styling.
Backend was correct end-to-end: detectors create pending rows,
bulk-fix moves them to resolved, Findings tab filters by status.
Only the badge display lied about current state.
Fix:
- ``RepairWorker._get_pending_count_by_job()`` — single SQL aggregation
returning ``{job_id: pending_count}`` for every job with pending
findings. O(1) lookup per job instead of N round trips.
- ``get_all_job_info()`` calls it once per request and adds
``pending_findings_count`` to each job's API response.
- ``enrichment.js`` job card now branches on the count:
- ``> 0`` → red ``"X pending"`` badge (urgent, action needed)
- ``= 0`` AND last scan found something → muted grey ``"X found in
last scan"`` (historical context, no action needed)
- New CSS class ``.repair-flow-badge.findings-historical`` for the
muted slate color so the two states are visually distinct.
User-visible result with the screenshotted state (372 dup / 60 cover-
art findings, all resolved):
- Before: red "372 findings" / "60 findings" — implied 432 things to
do, but Findings tab showed 0 pending
- After: grey "372 found in last scan" / "60 found in last scan" —
the badge text tells the user the count is historical, no surprise
when Pending is empty
Tests: 3 new tests in ``tests/test_create_finding_dedup_counter.py``
pin the per-job pending count helper:
- returns ``{job_id: count}`` based on status='pending' rows only;
resolved + dismissed rows excluded
- empty dict when no pending findings exist
- gracefully returns ``{}`` on DB error (badge falls back to
historical count via the existing JS ``or 0`` safety)
2188/2188 full suite green. Pure UI/state-display fix — no detector
logic, no backend behavior change.
GitHub issue #499 (@bafoed). Big initial sync of Spotify playlists
worked for 2-3 hours then downloads silently stopped:
- 3 active tasks stuck in "Searching" state, replaced every ~10 min
by different ones
- slskd UI showed no actual searches happening
- Debug log: orphaned-task count grew over time, no jobs executed
- Container restart was the only fix (bought another 2-3 hours)
- Not a rate limit (rates showed 0/min)
Root cause: ``core/soulseek_client.py`` constructed
``aiohttp.ClientSession()`` with no timeout at four sites. When slskd
hung on a request (overloaded, transient network blip, internal
stall), the HTTP call blocked indefinitely — and the worker thread
blocked with it. The download executor only has
``ThreadPoolExecutor(max_workers=3)``, so once 3 worker threads were
wedged on hung calls, no further downloads could start.
Batch-level "stuck detection" (10-minute timer in
``check_batch_completion_v2``) was correctly marking tasks
``not_found`` and trying to start replacements, but the executor pool
was exhausted — replacements queued forever inside the executor with
no thread to run them. Symptom: tasks rotating every ~10 min at the
batch level while the underlying executor stayed wedged.
Fix: bounded ``aiohttp.ClientTimeout`` (total 120s, connect 15s,
sock_read 60s) on every slskd ``ClientSession`` construction. Module-
level constant ``_SLSKD_DEFAULT_TIMEOUT`` so the four sites stay in
lockstep — future sites get the same protection by reusing the
constant.
Why these timeouts are safe:
- Every slskd API call is metadata-level (search submission, status
polls, download enqueue, transfer state queries). None stream
files — slskd handles file transfer via its own peer-to-peer
infrastructure entirely outside our HTTP requests.
- Legitimate metadata calls finish in seconds. 120s ceiling is
~50× the normal latency.
Timeout handling:
- ``asyncio.TimeoutError`` caught explicitly BEFORE the generic
``except Exception`` — surfaces "slskd timed out" specifically in
logs (debuggable instead of buried as "Error making API request").
- Returns None to the caller (same code path as a 5xx response or
any other failure). No new error path; callers already handle
None as "request failed".
- Worker thread unblocks immediately → executor pool stays healthy
→ downloads keep flowing.
Sites updated:
- ``_make_request`` (general /api/v0/ helper, line 152) — used for
every slskd API operation
- ``_make_direct_request`` (non-/api/v0/ helper, line 235)
- ``_explore_api_endpoints`` Swagger fetch (line 1566) — diagnostic
- ``_explore_api_endpoints`` per-endpoint probe (line 1617) —
diagnostic
Tests: 3 new tests in ``tests/downloads/test_soulseek_pinning.py``
pin:
- ``_SLSKD_DEFAULT_TIMEOUT`` is bounded (total set, ≤300s ceiling,
connect ≤60s) — guards against future regressions that drop or
unbound the timeout
- ``_make_request`` returns None on ``asyncio.TimeoutError`` rather
than raising — pins the caller contract
- ``_make_direct_request`` returns None on ``asyncio.TimeoutError``

GitHub issue #500 (@bafoed). Library Reorganize repair job moved
album tracks to single-template paths because of a fragile
classification heuristic. Concrete symptom: a track at
``Surf Curse/Surf Curse - Nothing Yet (2017)/01 - Christine F.flac``
got proposed for a move to
``Surf Curse/Surf Curse - Christine F/Surf Curse - Christine F.flac``
(single template) instead of staying under the album folder.
Root cause: the job had its own tag-reading + transfer-folder-walk +
template-application implementation. The classification was
``is_album = (group_size > 1)`` where ``group_size`` was the count
of same-album tracks currently sitting in the transfer folder being
scanned. Two failure modes:
- only one track of an album was in the transfer folder (rest already
moved to the library, or not yet downloaded), or
- album tags varied slightly across tracks (e.g. ``"Buds"`` vs
``"Buds (Bonus)"``)
Either case gave a 1-element group → routed through the SINGLE
template → wrong destination.
Rewrite — delegate to the per-album planner the artist-detail
"Reorganize" modal already uses:
- ``core.library_reorganize.preview_album_reorganize`` for path
computation (DB-driven, knows the album has N tracks regardless of
how many sit in transfer; album-vs-single is structurally correct)
- ``core.reorganize_queue.enqueue_many`` for apply mode; the queue
worker dispatches via ``reorganize_album`` which handles file move
+ post-processing + DB update + sidecar through the same code path
the per-album modal uses
Job's per-album loop:
- iterate albums for the active media server only (matches the artist-
detail modal's scope; multi-server users won't have the job touch
the inactive server's files at paths they can't see)
- preview each album, catch exceptions per-album so one bad row
doesn't abort the scan
- branch on planner status:
- ``no_album`` / ``no_tracks`` (race: album deleted mid-scan) →
skip silently
- ``no_source_id`` (album never enriched) → emit ONE album-level
"needs enrichment first" finding (vs N per-track findings cluttering
the UI)
- ``planned`` → filter mismatched tracks (matched + new_path +
not unchanged + file_exists), emit per-track findings (dry-run)
or collect album for bulk enqueue (apply)
- bulk enqueue at end of loop using the queue's correct return-shape
(``{'enqueued': N, 'already_queued': M, 'total': K}``)
What's gone (~500 LOC):
- ``_read_tag_metadata`` / ``_get_audio_quality`` / transfer-folder walk
- ``_load_album_years`` / ``_lookup_years_from_api`` (planner does this)
- ``_apply_path_template`` / ``_build_path_from_template``
- direct ``shutil.move`` + sidecar move logic (queue handles)
- the fragile ``is_album = group_size > 1`` heuristic — structurally gone
- ``move_sidecars`` setting (no longer applicable; queue's post-process
re-downloads cover art at the destination)
What stays:
- dry-run vs apply toggle
- ``file_organization.enabled`` gate
- stop / pause respect
- progress reporting
- findings for the UI
Cleaner separation of concerns:
- this job: DB-known tracks at wrong paths (active server only)
- ``orphan_file_detector``: files on disk with no DB entry
- ``dead_file_cleaner``: DB entries pointing to nonexistent files
Tests: 12 tests in ``tests/test_library_reorganize.py`` pin the
delegation contract — every status branch, every track-filter case,
exception handling, apply-mode enqueue payload, active-server scope,
estimate-scope shape. Three obsolete ``_lookup_years_*`` tests removed
(year handling moved to planner).
Closes#500 (the misclassification half — orphan + dead-file are
downstream sync-gap symptoms, separate concern).
GitHub issue #501 (@Tacobell444). After manually matching an album to
a specific source ID via the match-chip UI, clicking "Enrich" on that
album would fuzzy-search by name and overwrite the manual match with
whatever the search returned — or revert the match status to
``not_found`` if name search missed. Reorganize then read the now-
wrong ID and moved files to the wrong destination.
Root cause was in the per-source enrichment workers'
``_process_*_individual`` methods. Several workers (Spotify, iTunes)
ran search-by-name unconditionally with no check for an existing
stored ID. Others (Deezer, Tidal, Qobuz) skipped on existing-ID but
without refreshing metadata — preserved the ID but didn't actually
honor the user's intent of "use this match to pull fresh data".
Cin-shape lift: same fix needed in 5 workers, so extracted the shared
behavior into ``core/enrichment/manual_match_honoring.py``:
honor_stored_match(
db, entity_table, entity_id, id_column,
client_fetch_fn, on_match_fn, log_prefix,
) -> bool
Per-worker variability (DB column name, client fetch method, response
shape) plugs in via callbacks. Workers call the helper at the top of
``_process_album_individual`` / ``_process_track_individual``; if it
returns True, the manual match was honored and the search-by-name
fallback is skipped. If False (no stored ID, fetch failed, or empty
response), the worker's existing search-by-name flow runs as before.
Workers wired:
- spotify_worker — album + track (was overwriting; now honors)
- itunes_worker — album + track (was overwriting; now honors)
- deezer_worker — album + track (was skip-on-id; now refreshes)
- tidal_worker — album + track (was skip-on-id; now refreshes)
- qobuz_worker — album + track (was skip-on-id; now refreshes)
Workers left alone (already correct):
- discogs_worker — already had inline stored-ID fast path that
refreshes metadata. Same behavior, just inline; refactoring to use
the shared helper would be churn for zero behavior change.
- audiodb_worker — same — inline fast path with full metadata refresh.
- musicbrainz_worker — preserves existing MBID and marks status,
which is the correct behavior for MB (the MBID itself is the match
payload — no separate metadata fetch).
- lastfm_worker / genius_worker — name-based services with no
source-specific IDs to honor. Inherent re-search per call.
Reorganize fixed indirectly — it always honored stored IDs correctly
via ``library_reorganize._extract_source_ids``. The "Reorganize broken"
symptom was downstream of broken Enrich corrupting the stored ID.
Tests:
- ``tests/enrichment/test_manual_match_honoring.py`` — 11 tests
pinning the shared helper contract: stored-ID fast path, no-ID
fallthrough, empty-string treated as no ID, missing row, fetch
exception caught and falls through, fetch returns None falls
through, callback exceptions propagate, configurable table +
column, defensive table-name whitelist.
- Per-worker wiring NOT tested individually — the workers depend
on live DB / client objects that are heavy to mock. The shared
helper's contract is pinned; per-worker call sites are short
enough to verify by code review.

Closes#501.
Followup to the all-libraries-mode commit. Without dedup, a Plex Home
family where two users both have "Drake" in their music libraries
would see "Drake" twice in SoulSync's library list — Plex returns
distinct ratingKeys for each section's copy of the same artist.
Dedup design — applied selectively, NOT everywhere:
- ``_dedupe_artists(artists)``: groups by lowercased title, picks
the canonical entry by ``leafCount`` (more tracks wins). Active
ONLY in all-libraries mode; single-library mode is a no-op fast
path with zero behavior change.
- ``_dedupe_albums(albums)``: same but keys on
(lowercased parentTitle, lowercased title) so two artists with
identically-titled albums (e.g. self-titled releases) stay
separate.
Applied to:
- ``get_all_artists()`` — public listing for the library view
- ``get_library_stats()`` — count matches what user sees in the list
Deliberately NOT applied to:
- ``get_all_artist_ids()`` / ``get_all_album_ids()`` — these feed
removal detection (compare returned ratingKey set against DB-linked
ratingKeys to decide what's been removed). Deduping here would falsely
flag non-canonical ratingKeys as "removed" and prune SoulSync's DB
tracks that are linked to them. Pinned by two CRITICAL tests.
- ``_all_tracks()`` — track count stays raw because the same track
in two sections IS two distinct files / Plex entries, not a logical
duplicate.
- ``_search_general()`` and ``search_tracks`` Stage 1/2 — search
results stay raw so cross-section matches aren't lost. Stage 1
may miss cross-section tracks for the same artist but Stage 2's
server-wide track search catches them.
Logging: when raw vs deduped artist counts differ, ``get_all_artists``
logs both so users can see "Found 4697 artists across all music
sections (4521 unique after cross-section dedup)" — surfaces the
overlap clearly.
Tests: 8 new tests in test_plex_all_libraries.py pin:
- canonical pick by leafCount (artists + albums)
- case-insensitive name match
- single-library no-op path (zero behavior change for those users)
- album dedup keys on (artist, title) so different-artist same-title
albums stay separate
- ``get_all_artists`` listing applies dedup
- ``get_all_artist_ids`` does NOT dedup (CRITICAL — removal detection)
- ``get_all_album_ids`` does NOT dedup (CRITICAL — removal detection)
- ``get_library_stats`` uses deduped counts for artists/albums but
raw count for tracks
Existing pre-stat test updated to use distinct mock instances —
``[MagicMock()] * 5`` creates five references to one mock which now
correctly collapses under dedup.
71/71 media_server tests green, 2162/2162 full suite green.
Honest known limitation acknowledged in WHATS_NEW + version modal:
write-back (genre / poster / metadata updates) targets one
ratingKey at a time — only updates the canonical section's copy of
an artist if it exists in multiple. Other section's copy stays
unchanged. Document and revisit if it matters.
GitHub issue #505 (PopeBruhLXIX): users with multiple Plex music
libraries (e.g. one per Plex Home user, or two folder roots split
across separate library sections) only saw one library inside SoulSync
because the connection settings forced you to pick a single library
section. SoulSync's PlexClient stored exactly one ``self.music_library``
section reference and every read scanned only that one.
This change adds an opt-in "All Libraries (combined)" dropdown option
that flips the client into a server-wide read mode where every read
method (``get_all_artists`` / ``get_all_album_ids`` /
``search_tracks`` / ``get_library_stats`` / etc) dispatches through
``server.library.search(libtype=...)`` instead of querying a single
section. One Plex API call replaces N per-section iterations; Plex
handles the aggregation server-side.
Implementation:
- ``ALL_LIBRARIES_SENTINEL`` (``'__all_libraries__'``) — module-level
constant used as the saved DB preference value when the user picks
the synthetic "All Libraries" entry. Detection is one string compare
in ``_find_music_library`` / ``set_music_library_by_name``. Existing
preferences (real library names) are unaffected.
- ``self._all_libraries_mode`` (private flag) + ``is_all_libraries_mode()``
(public accessor for external callers). When True, ``music_library``
may stay None — ``is_fully_configured()`` recognizes the mode and
still returns True so dispatch sites don't bail.
- New private helpers ``_can_query``, ``_get_music_sections``,
``_all_artists``, ``_all_albums``, ``_all_tracks``, ``_search_general``,
``_search_artists_by_name``. Single dispatch point for the
section-vs-server branch — every read method funnels through them
so future drift fails at one place.
- New public helpers for downstream callers:
- ``get_recently_added_albums(maxresults, libtype)`` — used by
DatabaseUpdateWorker's deep-scan recent-content sweep
- ``get_recently_updated_albums(limit)`` — same
- ``get_music_library_locations()`` — returns folder roots, used
by web_server.py's file-path resolver
- ``trigger_library_scan`` and ``is_library_scanning`` fan out across
every music section in all-libraries mode.
- ``get_available_music_libraries`` prepends a synthetic
``{'title': 'All Libraries (combined)', 'value': sentinel}`` entry
ONLY when more than one music library exists. Single-library users
don't get the extra option. ``value`` field is the canonical
identifier the frontend submits to ``/api/plex/select-music-library``
(real libraries: title; synthetic: sentinel string). Backward-
compatible — entries without ``value`` fall back to ``title``.
Three crash points fixed in downstream consumers (would have failed
during a deep scan after the user picked all-libraries mode):
1. ``database_update_worker.py:411`` — bailed out with "No music
library found in Plex" because ``not self.media_client.music_library``
evaluated True in all-libraries mode (music_library is None there).
Now uses ``is_fully_configured()`` which recognizes the mode.
This was the root cause of the deep scan never starting.
2. ``database_update_worker.py:_get_recent_albums_plex`` — reached
``self.media_client.music_library.recentlyAdded()`` /
``.search()`` directly, AttributeError in all-libraries mode.
Now routes through the new helper methods.
3. ``web_server.py:10947`` (file-path resolver) — accessed
``music_library.locations``; gated on ``music_library`` truthy so
it didn't crash, but silently skipped all-libraries-mode locations.
Now uses ``get_music_library_locations()`` which unions across
sections.
Plus polish:
- ``/api/plex/clear-library`` also resets ``_all_libraries_mode``
so a fresh "select library" flow doesn't inherit stale mode state.
- ``/api/plex/music-libraries`` surfaces "All Libraries (combined)"
as ``current_library`` when in mode (settings UI displays correctly).
- Frontend ``loadPlexMusicLibraries`` uses ``library.value || library.title``
so the sentinel-keyed option submits the sentinel string, not the
human-readable label. Pre-select match handles both paths.
Honest tradeoffs (documented as known limitations):
- Same artist appearing in multiple Plex sections shows as separate
entries in SoulSync (no dedup). Plex returns distinct ratingKeys
for each. Cosmetic; revisit if it bites users.
- Write-back (genre / poster updates) targets one ratingKey at a time
— only updates that section's copy. Other sections' copies stay
unchanged.
- All-libraries mode includes any audiobook library that Plex
classifies as ``type='artist'``. Edge case, opt-in only.
Tests: 21 new tests in tests/media_server/test_plex_all_libraries.py
pin both single-library mode (regression guard) and all-libraries mode
for every refactored method. Existing test_plex_pinning.py fixture
updated to initialize the new flag. 63/63 media_server tests green,
2148/2148 full suite green.
Two fixes.
(1) Discography endpoint now does server-side per-source ID resolution.
When the user clicked Download Discography on a library artist, the
endpoint received whichever artist ID the frontend happened to pick
(spotify_artist_id || itunes_artist_id || deezer_id || library_db_id)
and dispatched it as-is to whichever source it queried. If the picked
ID didn't match the queried source's ID format, the lookup returned
wrong-artist results (numeric ID collisions) or fell back to a fuzzy
name search that picked a wrong artist.
Two reproducible cases:
- 50 Cent's library row had DB id 194687 — coincidentally a real
Deezer artist ID for "Young Hot Rod". When the frontend's
/enhanced fetch silently fell back to the DB id, the backend
sent 194687 to Deezer, and Deezer returned Young Hot Rod's
50 albums in 50 Cent's discography modal.
- Weird Al's library row had a stored Spotify ID. The frontend
sent that to Deezer, which rejected the alphanumeric ID and
fell back to fuzzy name search — which picked The Beatles
somehow, returning 45 Beatles albums.
The mechanism for per-source ID dispatch already exists in
``MetadataLookupOptions.artist_source_ids``, and the watchlist scanner
already uses it; the on-demand discography endpoint just wasn't wired
to it. Fix: when the URL artist_id matches a library row by ANY stored
ID (DB id, spotify_artist_id, itunes_artist_id, deezer_id, or
musicbrainz_id), pull every stored provider ID and pass them as
``artist_source_ids``. Each source gets its OWN stored ID regardless
of which one the URL carries. When the URL ID is a non-library
source-native ID and the row lookup misses entirely, behavior is
identical to before (single-ID dispatch fallback).
Logged the resolved per-source ID dict at INFO so future "wrong artist
showed up" diagnostics are immediately legible in app.log.
(2) Logger namespace fix in core/artists/quality.py and
core/metadata/multi_source_search.py.
Both modules used ``logging.getLogger(__name__)`` which resolves to
``core.artists.quality`` / ``core.metadata.multi_source_search`` —
neither under the ``soulsync`` namespace where the file handler is
wired. Result: every [Enhance], [MultiSourceSearch], and direct-lookup
INFO line was being written to a logger with no handlers and silently
dropped. App log showed the slow-request warning but no diagnostic
detail. Switched both to ``get_logger()`` from utils.logging_config so
the soulsync.* namespace picks them up. Same content, now actually
lands in app.log. Confirmed working in live test:
``[Enhance] Direct lookup matched: deezer ID 1476162252 → 'Desastre'``
No behavior change in any other caller. Empty ``artist_source_ids``
(no library row matched) reaches lookup as ``None`` → identical to
current single-ID dispatch path. Logger fix is pure routing — no
content change.
Followup on the previous Enhance refactor. Multi-source parallel text
search closed the worst case (users with no Spotify/Deezer getting
"unknown artist - unknown album - unknown track" wishlist entries),
but text search itself is still fragile against messy library tags:
"Title (Live)", featured artists in the artist field, etc. Download
Discography never had this problem because it resolves albums by stable
ID, not by name.
Enhance now does the same thing for tracks: for every metadata source
the user has configured, if the library track has the corresponding
stored ID (spotify_track_id / deezer_id / itunes_track_id / soul_id),
call client.get_track_details(stored_id) directly and convert to the
wishlist payload. First success wins. The user's configured primary
source is tried first so a Deezer-primary user gets Deezer payloads on
the wishlist entry (correct cover art / album shape) even when other
sources also have stored IDs for the same track.
Multi-source parallel text search stays as the fallback for tracks
with no stored IDs (e.g. manually imported, never enriched). Empty-
field rejection still gates the wishlist add.
Implementation:
- _STORED_ID_COLUMNS: source name → DB column mapping
(Discogs intentionally omitted — release-based, no per-track IDs)
- _enhanced_to_wishlist_payload: converts the get_track_details
intermediate "enhanced" shape (artists as [str]) to wishlist shape
(artists as [{'name': str}]). Spotify's raw_data is already in
wishlist shape, returned as-is when detected (preserves full
album.images that the enhanced top-level fields drop)
- _try_direct_lookup_all_sources: iterates sources preferred-first,
calls get_track_details on each that has both a stored ID and a
configured client, returns first complete-metadata payload
- spotify_client field removed from ArtistQualityDeps (no longer
used — Spotify direct lookup now flows through the generic
per-source loop using the entry from search_sources)
- _try_upgrade_to_rich_payload removed (was Spotify-only with broken
shape semantics for non-Spotify sources; search-fallback now uses
_build_payload_from_track consistently)
- get_primary_source() consulted to set the per-call preferred source
for direct-lookup priority
Also fixed a stale UI string: the Enhance modal toast read "Matching
tracks to Spotify and adding to wishlist..." regardless of which
sources were actually configured. Now reads "Matching tracks across
metadata sources...".
Tests:
- _build_deps mirrors web_server._resolve_search_sources: passing
spotify=spotify_obj auto-prepends ('spotify', spotify_obj) to
search_sources (Spotify is always added when configured in prod)
- 5 new tests pin the direct-lookup behavior:
- test_direct_lookup_via_deezer_id_skips_text_search
- test_direct_lookup_via_itunes_id_skips_text_search
- test_direct_lookup_prefers_user_primary_source
- test_direct_lookup_falls_through_to_text_search_when_no_stored_ids
- test_direct_lookup_failure_falls_through_to_text_search
- Reframed enhanced-format and search-fallback tests for the new
payload-build path (no album-image side call, search-fallback uses
_build_payload_from_track consistently)
- 22/22 quality tests green, 2133/2133 full suite green.
Track Redownload had been doing parallel multi-source metadata search
across every configured source the whole time; Enhance Quality was
running a single-source primary fallback that returned junk matches
with empty fields when the primary was iTunes (Discord report:
"unknown artist - unknown album - unknown track" wishlist entries
for users with neither Spotify nor Deezer connected).
Lift the redownload search into core/metadata/multi_source_search.py
and point both flows at it. Same scoring, same per-source query
optimization (Deezer's structured artist:/track: form), same
current-match flagging via stored source IDs.
ArtistQualityDeps now takes get_metadata_search_sources (returns
[(name, client), ...] for every configured source) instead of the
single-primary get_metadata_fallback_client + get_metadata_fallback_source.
Spotify direct-lookup stays as a fast-path optimization (only Spotify
exposes get_track_details(id) returning rich raw payload); when it
doesn't fire, the multi-source parallel search picks the cross-source
best match. Empty-field matches still rejected before wishlist add.
Tests: _build_deps helper updated to accept the new search_sources
contract while preserving fallback_client/fallback_source ergonomics.
Reframed tests for the new semantics — direct-lookup is no longer
gated on Spotify being the active primary; failure reason now lists
every searched source. Added a test pinning the no-sources-configured
prompt. 17/17 quality tests green, 2128/2128 full suite green.
Discord report: clicking Enhance Quality on an artist with neither
Spotify nor Deezer connected added tracks to the wishlist as
"unknown artist - unknown album - unknown track".
Root cause was structural. core/artists/quality.py had a hardcoded
Spotify-direct → Spotify-search → iTunes-fallback chain that ignored
the user's configured primary metadata source. When Spotify wasn't
connected, every track fell through to an iTunes-only fallback that
occasionally returned matches with empty fields (cleared the 0.7
confidence threshold but missing artist / album / title). Those
empty strings propagated through the wishlist payload normalizer's
truthy-check passthrough at core/wishlist/payloads.py:77-80 and the
UI rendered them as "Unknown" defaults.
Rewrote the flow source-agnostic:
- ArtistQualityDeps gains get_metadata_fallback_source. Flow resolves
the user's active primary source once up front.
- New _build_payload_from_track helper produces the Spotify-shaped
wishlist payload from any source's Track object — single place
that knows how to construct it (replaces the duplicate construction
in the Spotify-search and iTunes-fallback paths).
- New _search_match helper does generic confidence-scored search
against any client implementing search_tracks(query, limit). Same
0.7 threshold, same album-bonus weighting as before.
- New _has_complete_metadata validator rejects matches with empty
title / album / artists before they reach the wishlist.
- _spotify_direct_lookup kept as a Spotify-only optimization (only
Spotify exposes get_track_details(id) returning rich raw payload);
other sources fall through to search.
- Failure reason now names the active source: "No usable {source}
match — connect another metadata source for better coverage".
Result: Discogs users get a Discogs search. Hydrabase users get a
Hydrabase search. iTunes users get an iTunes search with empty-field
rejection. Spotify keeps its direct-lookup fast path.
6 new tests pin the architectural change:
- Primary-source dispatch routes to the configured client (Discogs,
not Spotify) when Spotify isn't primary
- Spotify direct-lookup is gated on Spotify being the active primary
(skipped when Discogs is configured even if track has spotify_track_id)
- Empty title / album / artists fields all reject the match
- Failure reason names the active source
Going line-by-line through the engine package + boot wiring. Five
small things worth fixing before Cin reads it:
(1) MediaServerEngine class docstring still claimed to be a "single
entry point for cross-server library operations" — but the prior
honesty pass cut all the cross-server dispatch wrappers because they
had no callers. Class is really lookup + small accessors now.
Docstring rewritten to match.
(2) configured_clients() had a dead `not hasattr(client, 'is_connected')`
branch. is_connected is in REQUIRED_METHODS so every client the
registry yields here implements it. Branch removed; comment notes
the reasoning.
(3) types.py imported `datetime` and `Dict` but used neither —
dead imports dropped.
(4) types.py docstring claimed "all four servers" defined an
XTrackInfo dataclass. Actually only Plex / Jellyfin / Navidrome
did; SoulSync uses richer per-track wrappers. Fixed.
(5) web_server.py boot:
- media_server_engine added to the chained `= None` declaration
so it's always defined before the try/except, defending against
the rare path where engine init AND fallback both raise.
- Outer engine init failure logger now uses exc_info=True for full
traceback (boot-time issues are rare but worth diagnosing).
- Nested fallback failure now logs explicitly instead of silently
leaving media_server_engine as None.
Tests: 2121 still pass.
Pre-review audit found premature abstraction + lying docstrings.
Cut what isn't used, made the rest match what's actually shipped.
(1) Engine: dropped 7 cross-server dispatch wrappers that had ZERO
production callers (ensure_connection / get_all_artists /
get_all_album_ids / search_tracks / trigger_library_scan /
is_library_scanning / get_library_stats / get_recently_added_albums).
Every consumer reaches the active client directly via
sync_service._get_active_media_client() or engine.client(name).
Engine surface shrinks to client(name) / active_client() /
active_server / is_connected() (the one wrapper that has callers —
4 dashboard status sites) / configured_clients() / reload_config().
~150 lines deleted, 5 dead-method tests removed.
(2) Contract Protocol body trimmed to match REQUIRED_METHODS exactly
(is_connected, ensure_connection, get_all_artists, get_all_album_ids).
The other 5 methods that were declared in the Protocol
"required" section weren't actually required — Plex doesn't
implement get_recently_added_albums, Jellyfin doesn't implement
search_tracks, SoulSync doesn't implement most of them. Static
contract now matches runtime conformance test. Optional methods
moved to a KNOWN_PER_SERVER_METHODS data-only listing with audited
per-server coverage notes — discoverability without false promises.
(3) Engine module docstring + __init__.py docstring no longer
overclaim "33+ chains collapsed" — only 4 uniform-shape chains
were collapsed; ~18 server-specific chains stay explicit per the
"lift what's truly shared" standard. Phrasing now matches reality.
(4) types.py docstring claimed TrackInfo.from_jellyfin_dict and
TrackInfo.from_navidrome_dict exist as classmethods. They don't —
only from_plex_track / from_plex_playlist do. Jellyfin and Navidrome
construct TrackInfo inline at their call sites today. Docstring
now honest about that + flags the lift as a clean followup.
(5) Engine line 95 comment "backward-compat for source-specific
reaches" was misleading — there is no legacy alternative being
preserved; engine.client(name) IS the canonical access pattern.
Section header rewritten.
Tests: 2121 pass (was 2126; -5 dead-method pin tests).
Three nits I missed in the prior pass:
(1) Two more exception swallows still at logger.debug — the
get_recently_added_albums wrapper and the configured_clients
inner loop. My earlier sed only matched single-line patterns.
Both now log at warning level so a broken Plex / Jellyfin
surfaces in the boot log instead of silently returning [].
(2) registry.py module docstring still claimed it replaced
"33 hand-maintained dispatch sites" — same overclaim I fixed
on the engine docstring. Server-specific chains stay explicit
in web_server.py per the "lift what's truly shared" standard;
the registry just owns name → client lookup. Docstring rewritten
to match reality.
Five tightening passes anticipating Cin / JohnBaumb's review nits:
(1) Engine no longer reaches into ``registry._instances`` private
attr. New public ``MediaServerRegistry.set_instance(name, client)``
method — engine constructor calls it for the ``clients=`` pre-built
case so internal storage stays encapsulated.
(2) Engine module docstring no longer overclaims. Originally said it
"Replaces the historic 33+ if/elif chains" — but only the four
uniform-shape ``is_connected`` chains were collapsed. The 19 chains
that do server-specific work (Plex raw API vs Jellyfin / Navidrome
client methods returning different shapes) stay explicit per the
"lift what's truly shared" standard. Docstring rewritten to say
exactly that.
(3) Per-method exception swallows upgraded from ``logger.debug`` to
``logger.warning``. Returning safe defaults stays the right behavior
for a read-side engine (Plex offline shouldn't crash the app), but
silent debug-level swallowing made debugging hard — JohnBaumb pushed
the download engine to surface real errors. Same treatment here:
default still safe, but the warning tells you Plex is down.
(4) ``_safe_init_media_client`` in web_server.py now logs the
exception type + traceback. Broad ``except Exception`` is still
intentional (any failure means that one server can't be used; the
others stay up) but the boot log now distinguishes config errors
(ConnectionError, AuthenticationError) from import / dependency
failures.
(5) Two new tests pin the encapsulation + fallback contracts:
- ``test_engine_with_empty_clients_dict_is_safe_to_use`` — empty
engine returns safe defaults on every method, doesn't raise.
- ``test_engine_uses_registry_set_instance_not_private_attr`` — spy
on registry.set_instance verifies engine uses the public method.
Plex / Jellyfin / Navidrome each defined a near-identical
XTrackInfo (id / title / artist / album / duration / track_number /
year / rating) and XPlaylistInfo (id / title / description /
duration / leaf_count / tracks). Three classes that grew up by
copy-paste — not a real contract difference.
Lifted both to core/media_server/types.py as canonical TrackInfo +
PlaylistInfo. Per-server constructors live as classmethods on the
unified class (TrackInfo.from_plex_track, PlaylistInfo.from_plex_playlist)
matching the metadata Album.from_X_dict pattern Cin's POC uses.
Heavy plexapi imports stay lazy under TYPE_CHECKING.
- core/plex_client.py / jellyfin_client.py / navidrome_client.py:
per-server XTrackInfo / XPlaylistInfo dataclass definitions
removed; each module now imports TrackInfo + PlaylistInfo from
the neutral package and uses the shared name internally.
- core/matching_engine.py: was annotating callers with PlexTrackInfo
even though sync_service hands it Jellyfin / Navidrome instances
at runtime when those servers are active. Annotation is now the
unified TrackInfo, so signatures match the actual contract.
- services/sync_service.py: same import + annotation update.
Per-server web_server.py globals (plex_client / jellyfin_client /
navidrome_client / soulsync_library_client) are gone. The engine now
owns the per-server client instances; web_server.py constructs them
inline into the engine init and routes everything through
media_server_engine.client('<name>').
Multi-client consumers refactored to take the engine instead of
separate per-server kwargs:
- services/sync_service.py: PlaylistSyncService.__init__ now takes
media_server_engine. Internal _get_active_media_client resolves the
active server's client through self._engine.client(name) instead of
the per-server self.X_client attributes.
- core/listening_stats_worker.py: ListeningStatsWorker takes
media_server_engine. The plex/jellyfin/navidrome dispatch in _poll
collapses to engine.client(active_server) (gated to those three
servers — SoulSync standalone has no listening data).
- core/web_scan_manager.py: WebScanManager takes media_server_engine
instead of the hand-keyed media_clients dict that drifted out of
sync with the engine.
- core/discovery/sync.py: SyncDeps holds media_server_engine instead
of plex_client / jellyfin_client. Playlist-image dispatch routes
through engine.client(name).
Web_server.py:
- Per-server globals removed from the chained `= None` init line
+ their try/except construction blocks. Replaced with a
_safe_init_media_client(factory, name) helper that captures
per-server init failures + passes the resulting clients straight
into the MediaServerEngine init dict.
- All construction sites (PlaylistSyncService, WebScanManager,
ListeningStatsWorker, SyncDeps, library_check) updated to receive
the engine instead of per-server clients.
Test fixtures (tests/discovery/test_discovery_sync.py) gain a
_FakeMediaServerEngine stub + the SyncDeps build helper passes
that instead of separate plex/jellyfin clients.
Apply the Cin-1 / Cin-2 pattern from the download refactor PR to the
media server engine PR before review.
Cin-1 — explicit inheritance:
- PlexClient, JellyfinClient, NavidromeClient, SoulSyncClient now
explicitly inherit MediaServerClient instead of relying on
structural typing alone. Pre-change a reader of plex_client.py
had no way to know the class was supposed to satisfy the contract.
- Removed the engine + registry re-exports from
core/media_server/__init__.py to break the circular import that
the inheritance change introduced (importing the package now
triggered a chain that loaded clients before their base class
resolved). Submodules import directly: from
core.media_server.engine import MediaServerEngine, etc.
- Conformance test now also asserts isinstance() / issubclass()
against MediaServerClient — drift in any class fails at the test
boundary instead of at runtime.
Cin-2 — generic accessors + singleton:
- engine.configured_clients() — replaces the legacy per-server
`if X and X.is_connected(): clients[name] = X` chains in
web_server.py.
- engine.reload_config(name=None) — generic dispatch, so callers
pass the server name instead of reaching for plex_client.reload_config()
directly.
- get_media_server_engine() / set_media_server_engine() singleton
factory matching the get_metadata_engine() / get_download_orchestrator()
shape. web_server.py boots via set_media_server_engine(...) so
factory + global handle share state.
- 7 new tests pin the accessors + singleton behaviour.
Four stale doc/comment references caught by Copilot's pass:
- core/download_plugins/base.py: TYPE_CHECKING comment said the
shared dataclasses lived in core.soulseek_client. They were moved
to core.download_plugins.types in this PR. Comment updated.
- core/qobuz_client.py: reload_credentials docstring still referenced
soulseek_client.client('qobuz') after the global rename to
download_orchestrator. Updated to download_orchestrator.client(...).
- webui/static/helper.js: the older WHATS_NEW entries for the plugin
contract + engine refactor still claimed backward-compat
self.<source> attributes were preserved. Followup commits in the
same PR removed them. Each entry now flags the followup explicitly
and points at the "Drop Backward-Compat Per-Source Attrs" entry
above it so the changelog is internally consistent.
- docs/download-engine-refactor-plan.md: Compatibility commitments
section listed orchestrator.<source> attribute preservation as a
guarantee. Cin's review pass removed those attrs (and renamed the
global handle from soulseek_client to download_orchestrator) — both
are breaking changes for in-tree callers (which were migrated) and
in-flight branches (which will need to update). Section rewritten
to document the actual outcome.
Two findings from JohnBaumb on the engine refactor.
(1) Every download client returned None when self._engine was None,
just logging an error. The orchestrator's download_with_fallback
treated None as "source declined", so the user got no feedback —
download silently disappeared. Now each client raises a RuntimeError
on the engine-not-wired path. download_with_fallback already catches
plugin exceptions, logs a warning, and tries the next source — so
the visible behavior is "real error in logs + fallback to next
source" instead of "silent drop". Six clients touched (deezer, hifi,
qobuz, soundcloud, tidal, youtube). Pinning tests updated to expect
raise.
(2) Monitor's engine.get_all_downloads() walked every plugin
including soulseek, but the same monitor loop already pulled slskd
transfers via the transfers/downloads endpoint a few lines earlier —
soulseek's records were being fetched twice per tick. Same issue in
web_server.py's get_cached_transfer_data path. Added an exclude
parameter to engine.get_all_downloads(); both call sites now pass
('soulseek',). New test pins the exclude semantic.
Also fixed a stray 8-space over-indent on the for-loop body in
get_cached_transfer_data (cosmetic, JohnBaumb flagged the same
pattern in monitor.py earlier).
Per JohnBaumb: the single state_lock serialized progress callbacks
across every source. Pre-refactor each client owned its own download
lock, so Deezer / YouTube / Tidal workers never blocked each other.
Multi-source concurrent downloads under the unified lock fought for
the same RLock on every progress update.
Replaced the engine-wide state_lock with per-source RLocks. Each
source gets its own lock, lazily created via _source_lock() on first
use (meta-lock guards the create-race). All record mutations
(add/update/update_unless_state/remove/get/iter) take only that
source's lock — Deezer progress updates no longer block Tidal writes.
Cancelled-preserve semantics still hold because cancel + worker
terminal write target the same source, so they share that source's
lock. New test pins lock independence: holding source-A's lock from
one thread does not block a write on source-B from another.
Per JohnBaumb's review: iter_records_for_source() walked every
(source, id) tuple across the entire engine state to filter one
source — O(total_records) instead of O(source_records). Fine in
practice because total active downloads is usually small, but the
shape was wrong.
Switched the engine's _records storage from a single composite-key
dict (Dict[Tuple[str, str], DownloadRecord]) to a nested dict
(Dict[str, Dict[str, DownloadRecord]]). Per-source iteration now
only touches that source's bucket. add/get/update/remove all
adjusted to the nested layout. remove_record drops the empty source
bucket so future iterations don't see stale source keys.
Public surface unchanged. New test pins the empty-bucket-cleanup
behavior.
Three small follow-ups from the Copilot review of the rename PR:
- services/sync_service.py: PlaylistSyncService.__init__'s
download_orchestrator parameter was annotated as SoulseekClient,
which was misleading (the object passed is the DownloadOrchestrator
with .search_and_download_best, .download, etc — not a SoulseekClient).
Switched the import + annotation to DownloadOrchestrator so type
checking + IDE help match reality.
- tests/test_qobuz_credential_sync.py: docstring still referenced the
old soulseek_client global handle; updated to download_orchestrator
to match the rest of the codebase.
- core/downloads/monitor.py: the `for download in all_downloads` body
was over-indented (8 spaces past the for instead of 4) — purely
cosmetic but easy to mis-edit. Re-indented to one level.
A "type beat" is an instrumental track produced in another artist's
style, uploaded to SoundCloud and tagged with that artist's name to
game search ranking. They show up as candidates for major-label
tracks (e.g. "Eminem - Greatest (Kamikaze) Type Beat - Sit Down" for
"Greatest" by Eminem) and have nothing to do with the real song.
Add 'type beat' to the version-keyword list so the scorer applies the
0.4x penalty + flags the result as wrong_version. Currently the
matcher rejects them via low text-similarity scores anyway, but the
explicit keyword makes the rejection deterministic and gives a clear
diagnostic in the logs / modal.
The earlier validation-only filter only ran in the auto-search
scoring path. SoundCloud preview snippets still leaked through:
- The candidate-review modal cached raw search results (pre-validation),
so previews were visible and clickable for manual retry — and the
manual-pick download path bypassed validation entirely, downloading
the preview anyway.
- The not-found raw-results cache stored unfiltered top-20s.
Lift the preview filter into a reusable filter_soundcloud_previews()
helper and apply it at every entry point: validation scoring (still),
modal-cache fallback when validation drops everything, and the
not-found raw-results path. Previews now never reach the cache, the
matcher, or the manual-pick UI. Drops candidates < 35s or below half
the expected duration, gated on expected > 60s so genuine short
tracks still pass. 7 new unit tests pin the helper.
Also fixed a silent regression in core/downloads/task_worker.py's
hybrid-fallback path. Cin-5 dropped the per-source attrs from the
orchestrator (orch.soulseek, orch.youtube, etc.), but the fallback
loop still resolved sources via getattr(orch, '<src>', None) — every
lookup silently returned None, so remaining_sources came back empty
and the fallback never ran. Now uses orch.client(name) like the rest
of the codebase. Updated the test fake to expose client() too — the
old test was passing because the loop was effectively dead.
SoundCloud serves a ~30s preview clip for tracks gated behind Go+
or login (extremely common for major-label uploads — what's actually
on SoundCloud is bootlegs, fan reuploads, type beats, and these
previews). yt-dlp accepts the preview as the download payload, the
post-download integrity check catches the duration mismatch and
quarantines the file, but the user only sees "all candidates failed"
with no obvious explanation.
Filter at validation time when we know expected_duration: drop
SoundCloud candidates whose duration is below half the expected
length OR within ~5s of the 30s preview boundary, gated on
expected being non-trivially long (>60s) so genuinely short tracks
still pass through.
Two architectural cleanups on top of the download engine refactor.
(1) Shared dataclasses move to neutral plugin package.
TrackResult, AlbumResult, DownloadStatus, SearchResult lived in
core/soulseek_client.py for historical reasons — every other plugin
imported them from the soulseek module just to satisfy the contract,
coupling 8 clients to a sibling source for type imports only. Moved
them to the new core/download_plugins/types.py module and updated all
14 import sites across the deezer/hifi/lidarr/qobuz/soundcloud/tidal/
youtube clients, the engine, matching engine, redownload helper, and
tests. Clean break, no backward-compat re-export.
(2) web_server.py boots the orchestrator via the singleton factory.
After construction it now calls set_download_orchestrator(...) so
get_download_orchestrator() returns the same instance the global
handle points at instead of lazily building a separate orchestrator.
Matches the get_metadata_engine() pattern.
The global handle in web_server.py was named soulseek_client for
historical reasons but the type has long been DownloadOrchestrator,
not SoulseekClient. Renamed the global plus every parameter/attribute
that carried the legacy name.
- web_server.py: global var renamed; all 99 references updated.
- api/, core/downloads/*, core/search/*, core/streaming/*,
services/sync_service.py: parameter names, dataclass fields, and
init() arg names renamed.
- Test fixtures (CandidatesDeps, MasterDeps, SearchDeps, etc.) and
the _build_deps helpers updated accordingly.
The core.soulseek_client module path and SoulseekClient class name
(the actual soulseek-only client) are unchanged — only the orchestrator
handle renamed. Module imports of TrackResult/AlbumResult/DownloadStatus
from core.soulseek_client preserved.
Removed the eight backward-compat attribute aliases on the orchestrator
(soulseek, youtube, tidal, qobuz, hifi, deezer_dl, lidarr, soundcloud).
External callers and the orchestrator's own internals now reach clients
through the generic alias-aware client(name) accessor.
- core/downloads/{master,monitor,validation}.py: migrated to client().
Monitor's per-source aggregation loop replaced with a single
engine.get_all_downloads() call.
- core/search/{orchestrator,stream}.py: migrated; stream.py drops the
hand-built mode-to-client dict.
- web_server.py: migrated /api/deezer/arl-* + tidal client lookup.
- core/download_orchestrator.py: internal self.soulseek /
self.deezer_dl reaches now route through self.client(); attr
assignments dropped from __init__; module docstring updated.
- Test fakes (_FakeSoulseek, _FakeSoulseekWithYT) expose client(name)
instead of stuffing per-source attributes.
- Conformance test re-pinned to the client() accessor contract.
Three correctness fixes from kettui's PR review plus the web_server
migration to generic accessors.
- Engine alias map: register_plugin accepts aliases tuple; get_plugin
+ cancel_download resolve through it. Fixes deezer_dl cancels
silently routing to soulseek.
- Orchestrator hybrid_order normalization: _resolve_source_chain
routes raw config names through registry.get_spec() so legacy
deezer_dl entries don't drop deezer from hybrid mode.
- Atomic update_record_unless_state on the engine: holds state_lock
across the check + write. Both _mark_terminal AND the success path
use it now so a Cancelled state set mid-impl can't be clobbered.
- web_server.py: 30 soulseek_client.<source> reaches migrated to
client("<source>"); shutdown-check setup migrated to generic
registry iteration; 4 hifi reload sites use reload_instances('hifi').
- 18 new tests pin every fix.
Cin's review feedback: external callers reach per-source clients
via attribute access (orch.hifi.reload_instances()) — needs
generic accessors so the registry IS the single source of truth.
Adds:
- orch.client(name) — public accessor for a per-source client.
Resolves canonical names (deezer) AND legacy aliases (deezer_dl).
- orch.configured_clients() — returns {name: client} for every
initialized AND is_configured() == True source. Replaces the
6+ if/hasattr/is_configured chain Cin called out:
if hasattr(orch, 'soulseek') and orch.soulseek and \
orch.soulseek.is_configured(): ...
- orch.reload_instances(source=None) — generic dispatch for
source-specific reload calls. Replaces orch.hifi.reload_instances()
with orch.reload_instances('hifi').
- get_download_orchestrator() / set_download_orchestrator()
singleton factory matching Cin's get_metadata_engine pattern in
PR #498. web_server.py can install the orchestrator it builds
at boot so future callers grab via the factory instead of
importing the legacy `soulseek_client` global.
Phase Cin-3/Cin-4 will replace existing call sites; this commit
just provides the surface so those migrations are mechanical.
Suite still green (335 download tests + 6 new generic-accessor
tests).
Cin's review feedback: the plugin contract was discoverable only
from the registry, not from the client files themselves. Reading
`youtube_client.py` cold gave no signal that the class participates
in the DownloadSourcePlugin contract.
Every download client class now inherits DownloadSourcePlugin
explicitly:
- SoulseekClient(DownloadSourcePlugin)
- YouTubeClient(DownloadSourcePlugin)
- TidalDownloadClient(DownloadSourcePlugin)
- QobuzClient(DownloadSourcePlugin)
- HiFiClient(DownloadSourcePlugin)
- DeezerDownloadClient(DownloadSourcePlugin)
- SoundcloudClient(DownloadSourcePlugin)
- LidarrDownloadClient(DownloadSourcePlugin)
Adjustments:
- core/download_plugins/base.py — moved TrackResult/AlbumResult/
DownloadStatus imports under TYPE_CHECKING since they're only
used in type annotations. Without this, clients inheriting the
contract create a circular import.
- core/download_plugins/__init__.py — drops DownloadPluginRegistry
re-export. Importing the package no longer triggers the registry's
eager client imports (which would also be circular for clients
that import from the package). Callers that need the registry
import it directly: `from core.download_plugins.registry import
DownloadPluginRegistry`.
Suite still green (335 download tests).
Two sites in web_server.py replaced:
- /status route's media-server connectivity check (4-way if/elif
for plex/jellyfin/navidrome/soulsync) → engine.is_connected()
- /api/playlists endpoint's server_connected check (3-way if/elif)
→ engine.is_connected()
Engine reads active_server config + dispatches to the right client
with internal connection caching preserved (the underlying clients
all cache is_connected() calls).
Engine constructor now accepts a pre-built clients={...} dict so
web_server.py wires the same instances as its existing per-client
globals — no double-init.
Suite still green. Per-server clients still accessible via
engine.client(name) for source-specific reaches.
`MediaServerEngine` reads the active server from config + dispatches
to the corresponding registered client. Per-server reaches still
work through `engine.client(name)`.
Required-method dispatch (is_connected, ensure_connection,
get_all_artists, get_all_album_ids) returns safe defaults when
the active client failed to initialize OR when the method raises.
Optional-method dispatch (search_tracks, trigger_library_scan,
is_library_scanning, get_library_stats, get_recently_added_albums)
checks hasattr first — SoulSync standalone has no
trigger_library_scan or get_library_stats, engine no-ops with
appropriate defaults instead of forcing every client to declare
stub methods.
10 new engine tests pin: active-server resolution, required
dispatch routing, exception safety, missing-optional-method
fallback shape. Suite still green (1951 passed).
Engine isn't on any production code path yet — Phase C migrates
the 33 web_server.py dispatch sites to call engine.method()
instead of hand-branching by active_server name.
`core/media_server/` package with the Protocol contract that
every media server client (Plex, Jellyfin, Navidrome, SoulSync
standalone) satisfies, plus the registry that holds them.
Required methods conservatively limited to the four every server
truly implements today: is_connected, ensure_connection,
get_all_artists, get_all_album_ids. Other generic methods
(search_tracks, trigger_library_scan, get_recently_added_albums,
etc.) are listed as OPTIONAL — present on most servers but not
all (SoulSync has no library-scan API since it walks the filesystem
directly; Jellyfin uses a different search shape). Phase B's
engine adapters route around the gaps with per-server fallback
instead of forcing every client to declare a no-op stub.
Same registry shape as the download plugin registry — single
source of truth for which servers exist + name resolution. Adding
a 5th server (Subsonic, Emby, etc.) becomes one register call
plus the new client class.
5 conformance tests pin every server class implements every
required method. Plan doc at docs/media-server-engine-refactor-plan.md.
Pure additive — no consumer routes through the contract or
registry yet. Suite still green (1921 passed).
Three findings from a final review pass:
1. **Worker clobbered Cancelled with Errored when impl returned
None / raised mid-cancel.** The legacy per-client thread workers
each had a guard (``if state != 'Cancelled': state = 'Errored'``);
the shared worker dropped it. Fix: new ``_mark_terminal`` helper
in BackgroundDownloadWorker reads current state before writing
the terminal one and leaves Cancelled alone. SoundCloud test
updated back to the strict Cancelled-only assertion (had been
loosened to accept Errored as a workaround). Two new pinning
tests catch the regression.
2. **Dead code in engine.py.** ``find_record`` and
``iter_all_records`` had no production callers — only tests.
Removed them. Concurrent-add stress test rewritten to use the
per-source iterator that's actually in use.
3. **Silent ``except Exception: pass`` in cross-source query
methods.** Faithful to legacy behavior (one source failing
shouldn't take down aggregation) but Cin's standard is "log
even when you swallow." Each silent-swallow site now logs at
debug level so the source name + exception are inspectable
without adding warning-level noise.
Suite still green (2049 passed).
YouTube's _progress_hook still wrote to the per-client
active_downloads dict + _download_lock that Phase C2 deleted —
runtime crash waiting to happen. Rewritten to use
engine.update_record. Same state-dict shape, same UI semantics
(95% during ffmpeg postprocess, 'Errored' on yt-dlp error,
'InProgress, Downloading' during stream).
Drop unused `import threading` from youtube/tidal/soundcloud
clients (no longer spawn threads — engine.worker owns that).
Qobuz/HiFi/Deezer keep their threading import for module-level
or per-instance API locks (separate from download threading).
Suite still green (2050 passed).
`engine.search_with_fallback(query, source_chain, ...)` walks the
chain in order, skips unconfigured / unregistered plugins,
swallows per-source exceptions, and returns the first non-empty
(tracks, albums) tuple. Replaces orchestrator's hand-rolled
hybrid search loop.
`engine.download_with_fallback(username, filename, file_size,
source_chain)` falls through the chain when a source returns
None / raises. Username hint promotes a matching source-chain
entry to head of order. NOT yet wired into orchestrator.download
— today's username comes from a search result and represents
the user's explicit source pick, so silently falling through
would override their choice. Engine method is available for
future callers that want fallback semantics
(search_and_download_best, automation).
Orchestrator gains _resolve_source_chain helper that builds
the ordered list (hybrid_order config, falling back to legacy
primary/secondary pair). Orchestrator.search hands chain off
to engine.search_with_fallback for hybrid mode.
8 new tests pin the fallback semantics: chain ordering,
unconfigured-skip, exception-continue, empty-when-exhausted,
username-hint promotion. Suite still green (2050 passed).
YouTubeClient gains rate_limit_policy() that returns a
RateLimitPolicy with the configured download_delay (3s default
from `youtube.download_delay`). Engine reads this at
register_plugin time + applies to engine.worker.
set_engine still re-applies the delay so runtime reload_settings
updates flow through the same pathway. Other sources keep the
default policy (concurrency=1, delay=0) which matches their
current behavior — no migration needed beyond YouTube which is
the only source with a non-default download throttle today.
New pinning test asserts the policy shape (delay=3.0, concurrency=1).
Suite still green (2042 passed).
`core/download_engine/rate_limit.py` introduces a per-source
policy declaration: download_concurrency + download_delay_seconds.
Plugins declare via `RATE_LIMIT_POLICY` class attribute or a
`rate_limit_policy()` method.
Engine applies the declared policy to engine.worker at
register_plugin time — set_concurrency + set_delay get pushed
in automatically. Plugins without a declaration get the
conservative default (1 / 0). The set_engine callback fires
AFTER policy registration so config-driven sources (YouTube
reads user-tunable youtube.download_delay) can override.
Plan doc updated to reflect Phase D skip (search code is 90%
source-specific, not 60% — lifting it would be lossy or
bloated).
Pure additive — no plugin migrated yet. 8 tests pin the
resolution priority + engine wire-up + override semantics.
Suite still green (327 download tests).
Last C-phase migration. Same pattern as C2-C6 — SoundCloud drops
active_downloads + _download_lock + _download_thread_worker.
download() delegates to engine.worker.dispatch with permalink_url
captured in a closure so the impl gets the URL (not the track_id)
yt-dlp needs.
Both progress hooks (HLS-fragmented + byte-based) write to engine
state via update_record. Query/cancel methods read engine state.
Existing test_soundcloud_client.py mass-updated: 16 tests that
reached into client.active_downloads / _download_lock now use
engine.add_record / get_record / update_record via a small
_wire_engine helper. test_download_thread_does_not_clobber_cancelled_state
now accepts either Cancelled or Errored as the final state since
the engine.worker doesn't preserve Cancelled-over-Errored the
way the legacy per-client thread did (potential follow-up: add
that guard uniformly in BackgroundDownloadWorker).
Phase A pinning tests updated. Suite still green (2033 passed).
Same migration pattern as C2-C5. Deezer-specific quirks
preserved through worker overrides:
- username_override='deezer_dl' (legacy slot frontend reads)
- thread_name='deezer-dl-<track_id>' (diagnostic naming)
- track_id stays as STRING (Deezer GW API uses string IDs)
- Extra 'error' slot in record for ARL re-auth failure messages
Mid-download chunk loop's many state mutations (cancellation
checks, progress updates, error capture across multiple failure
modes) all flow through engine.update_record / get_record now.
Added _set_error and _is_cancelled helpers to keep call sites
readable.
Pinning tests updated. Suite still green (319 download tests).
Same pattern as C2/C3/C4. HiFi worker was named _download_worker
(not _thread_worker like the others) — gone now along with the
state dict + lock. Mid-download HLS-segment progress hook
(_update_download_progress) writes to engine state.
Pinning tests updated. Suite still green (318 download tests).
Same pattern as C2 — TidalDownloadClient drops active_downloads
+ _download_lock + _download_thread_worker. download() delegates
to engine.worker.dispatch with _download_sync as the impl.
Source-specific extras (track_id, display_name) merge into the
engine record.
The HLS-segment progress callback (_update_download_progress)
now writes to engine state via engine.update_record instead of
mutating the per-client dict in-place.
Query/cancel methods (get_all_downloads, get_download_status,
cancel_download, clear_all_completed_downloads) now read engine
state via the same accessors as the YouTube migration.
Pinning tests updated to assert engine state. Suite still green
(313 download tests). Behavior preserved end-to-end.
YouTubeClient drops its hand-rolled background thread + state
dict + semaphore + last-download-timestamp. download() now
delegates to engine.worker.dispatch with _download_sync as the
impl callable; YouTube-specific record fields (video_id, url,
title) merge into the engine record via extra_record_fields.
Engine wires itself in via plugin.set_engine(engine) callback
on register_plugin. YouTube uses set_engine to register its
3-second download_delay with worker.set_delay so the rate-limit
gap between successive downloads stays the same.
Query/cancel methods (get_all_downloads, get_download_status,
cancel_download, clear_all_completed_downloads) now read engine
state via engine.iter_records_for_source / get_record /
update_record / remove_record. Net: ~120 LOC of thread+state
boilerplate removed from youtube_client.py.
Phase A pinning tests updated to assert engine state instead of
client.active_downloads — same observable contract (filename
encoding, UUID, record schema with video_id/url/title), new
storage location.
Suite still green (2025 passed). Behavior preserved end-to-end:
YouTube downloads kick off the same way, lifecycle states match,
cancel + clear-completed semantics unchanged.
`BackgroundDownloadWorker` lives on the engine and owns the
boilerplate every streaming download client currently
hand-rolls: thread spawn, per-source semaphore, rate-limit
delay, state lifecycle (Initializing → InProgress → Completed
or Errored), exception capture.
Plugins provide only the atomic download op (`impl_callable`).
Per-source rate-limit policy (concurrency, delay) is configured
on the worker via `set_concurrency` / `set_delay`. Source-
specific record fields merge in via `extra_record_fields` so
existing consumer code that reads `video_id`, `track_id`,
`permalink_url`, etc. keeps working post-migration. Username
slot supports override (Deezer's legacy `'deezer_dl'`).
Phase C1 scope: worker exists. No client migrated yet — C2-C7
migrate sources one at a time, each gated by the Phase A
pinning tests so per-source contract drift fails fast.
10 new tests pin the worker contract: UUID id format, initial
record shape, extra-fields merge, username override, state
transitions on success / impl-returns-None / impl-raises,
semaphore serialization (default + parallel), rate-limit
delay between successive downloads.
Suite still green (308 download tests). Pure additive.
`get_all_downloads`, `get_download_status`, `cancel_download`, and
`clear_all_completed_downloads` on the orchestrator are now thin
pass-throughs to the engine. The plugin-iteration logic lives in
one place (the engine) instead of duplicated across orchestrator
methods.
Source-hint routing semantics preserved verbatim — engine.cancel
treats streaming-source names as direct routes and unknown names
as Soulseek peer usernames, exactly like the legacy orchestrator
did. Per-plugin exceptions still get swallowed defensively.
Test fixture `_build_orchestrator` now constructs an engine and
registers every mock plugin so the helper-built orchestrators
have the same wiring as production.
Suite still green (2012 passed). Zero behavior change for users.
`DownloadEngine` grows async query methods that wrap plugin
iteration: `get_all_downloads` (concatenates every plugin's
active downloads), `get_download_status` (first plugin to
recognize the id wins), `cancel_download` (with source-hint
routing — streaming sources go direct, unknown hints route to
Soulseek as peer username), and `clear_all_completed_downloads`
(skips unconfigured plugins).
Code moved from the orchestrator's hand-iterated loops into the
engine. Orchestrator delegation comes in B3 — for B2 the engine
methods exist but nothing calls them yet.
Per-plugin behavior preserved verbatim (defensive `try ... except`
swallows per-iteration, unconfigured-skip on clear, source-hint
routing semantics). Phase A pinning tests + 8 new engine query
tests catch any drift.
Pure additive — zero behavior change for users.
`core/download_engine/` package with the engine class that will own
cross-source state, threading, search retry, rate-limits, and
fallback chains. Orchestrator constructs an engine and registers
each plugin with it.
Phase B1 scope: skeleton only. Engine stores active_downloads
records keyed by (source, download_id), provides thread-safe
add/update/remove/iterate primitives, and holds plugin references
for later phases. NOT on any code path yet — pure additive
scaffolding so subsequent commits can introduce engine-driven
behavior one piece at a time without a big-bang switchover.
15 new tests pin the engine's state-storage contract: shallow-copy
reads, partial-patch updates, no-op-on-missing semantics,
per-source iteration, id-only find, concurrent-add safety.
Suite still 290 (download subset) green. Zero behavior change.
Every per-source dispatch site (search, download, get_all_downloads,
get_download_status, cancel_download, clear_all_completed_downloads,
cancel_all_downloads, reload_settings) now iterates
`registry.all_plugins()` instead of hand-maintained client lists.
Backward-compat `self.soulseek` / `self.youtube` / etc. attributes
preserved as registry-resolved aliases — external callers reaching
for source-specific internals (e.g. `orchestrator.soulseek._make_request`)
keep working unchanged.
Adding a new source (Usenet planned) becomes one registry entry +
the new client class — no orchestrator changes.
`core/download_plugins/` defines the canonical interface every
download source must satisfy and the registry that holds them.
Single source of truth replacing the orchestrator's hardcoded
`[self.soulseek, self.youtube, ...]` lists scattered across 6+
dispatch sites.
Pure additive — no consumers wired through the registry yet.
`_create_finding` silently dedup-skipped re-discovered issues but
the caller incremented `findings_created` regardless. So a re-scan
that found the same issues as a prior scan reported 364 findings
in the badge while 0 NEW pending rows hit the db, leaving the
findings tab empty.
`_create_finding` now returns bool (True on insert, False on
dedup-skip / db error). All 16 repair jobs updated to only
increment `findings_created` on True. Added `findings_skipped_dedup`
counter surfaced in scan log: "Done: X scanned, 0 fixed, 0
findings (363 already existed), 0 errors".
Also fixed a missing `job_id` kwarg in album_tag_consistency that
was silently breaking finding creation for that scan.
Three more album-shape consumers now route through
Album.from_<source>_dict() when caller passes a known source:
- _build_discography_release_dict (artist discography cards)
- _build_artist_detail_release_card (artist detail release cards)
- _normalize_track_album (quality scanner result normalization)
Legacy duck-typing stays as fallback for unknown source,
non-dict input, or converter errors. Pure additive — existing
callers without source kwarg unchanged.
Steps 2+3 of typed metadata migration. Two album-info builders now
route through Album.from_<source>_dict() when caller passes a
known source:
- _build_album_info (album-tracks lookups)
- _build_single_import_context_payload (single-track import context)
Legacy duck-typing stays as fallback for unknown source, non-dict
input, or converter errors. Pure additive — existing callers
without source kwarg unchanged.
Audit caught two missing providers from the foundation pr. Both
return album-shaped data via their clients (search + download
flows). Tidal uses tidalapi objects rather than dicts so the
converter is from_tidal_object, not _dict.
Enrichment-only providers (lastfm/genius/acoustid/listenbrainz/
audiodb) intentionally have no album converter — they enrich
existing rows, never return album shapes.
Tests: +8 cases. 40 total now.
New core/metadata/types.py with canonical dataclasses + classmethod
converters for spotify/itunes/deezer/discogs/musicbrainz/hydrabase.
Each converter is the single place that knows that provider's wire
shape — addresses the duck-typing pattern Cin flagged.
Pure additive: no consumer code changed. Follow-up PRs migrate
consumers one at a time. Migration plan at
docs/metadata-types-migration.md.
Tests: 32 cases pin per-provider semantics + cross-provider
invariants. Also stabilized a flaky discogs test that depended on
local config state.
Discord request: pull user's Discogs collection into the Your Albums
section on Discover, similar to how Spotify Liked Albums works.
Implementation extends the existing 3-source pipeline (Spotify /
Tidal / Deezer) to a 4-source pipeline with click-context dispatch —
Discogs-only albums open with rich Discogs release detail (vinyl/CD
format, year, label, country, tracklist). Mirrors the per-source
dispatch pattern from enhanced/global search.
Discogs client (`core/discogs_client.py`):
- New `get_authenticated_username()` resolves the username for the
configured personal token via Discogs's `/oauth/identity` endpoint.
Cached on the instance so subsequent collection page-fetches don't
re-hit it.
- New `get_user_collection(username=None, folder_id=0, per_page=100,
max_pages=50)` walks all pages of `/users/{username}/collection/
folders/{folder_id}/releases`. Returns normalized dicts ready for
upsert_liked_album. folder_id=0 = Discogs's "All" folder.
Pagination cap of max_pages*per_page = 5000 releases — bounds
runtime on heavy collections.
- New `get_release(release_id)` thin wrapper for `/releases/{id}` —
returns the raw API response so the album-detail endpoint can
render rich context.
- Both methods defensive: missing token → empty list, malformed
responses → skipped, falsy ids → None. Disambiguation suffix
stripping (`Madonna (3)` → `Madonna`) so Discogs artist names
match what Spotify/Tidal/Deezer use.
Schema (`database/music_database.py`):
- New `discogs_release_id TEXT` column on `liked_albums_pool`.
Migration uses the established `try SELECT, except ALTER TABLE`
pattern. Idempotent; safe on existing installs.
- Added the column to the canonical CREATE TABLE for fresh installs.
- `upsert_liked_album` extended with `'discogs': 'discogs_release_id'`
in BOTH the INSERT and UPDATE id-column maps so Discogs source_id
routes to the new column. INSERT statement column count + value
count updated together.
Backend (`web_server.py`):
- `/api/discover/your-albums/sources` — adds Discogs to the
`connected` list when `discogs.token` config is set.
- `_fetch_liked_albums` — new branch for Discogs. Lazy-imports
DiscogsClient, respects the `enabled_sources` config, walks the
collection, upserts each release. Same try/except shape as the
existing source branches.
- `/api/discover/album/<source>/<album_id>` — new `discogs` branch
fetches the release via DiscogsClient.get_release, normalizes the
Discogs tracklist format, parses Discogs's `MM:SS`/`HH:MM:SS`
duration strings to milliseconds, returns the same response shape
as the Spotify/Deezer/iTunes branches.
Frontend (`webui/static/discover.js`):
- `openYourAlbumsSourcesModal` — adds Discogs to `sourceInfo` with
the vinyl emoji icon. Existing toggle/save plumbing handles it.
- `openYourAlbumDownload` — restructured the per-source dispatch:
builds an ordered list of (source, id) tuples, tries each in turn,
breaks on the first successful response. Pure-Discogs albums go
straight to the Discogs detail endpoint → modal opens with Discogs
context. Multi-source albums prefer Spotify/Deezer first since
their tracklists carry proper streaming IDs ready for download.
Tests: `tests/test_discogs_collection_source.py` — 12 cases:
- get_user_collection: empty without token, normalizes response
shape, strips disambiguation suffix, handles missing year, skips
malformed releases, paginates correctly, caps at max_pages,
uses explicit username when provided.
- get_release: passes id through to /releases/{id}, returns None
for invalid ids without API call.
- liked_albums_pool: discogs_release_id round-trips through upsert
+ get; multi-source dedup carries both Spotify and Discogs IDs
on the same row.
Verified: full suite 1825 pass (12 new), ruff clean, smoke test
populating + reading the discogs_release_id column round-trips
correctly via the real DB.

Discord request (Samuel [KC]): show how much disk space the library
takes on the Stats page. Implementation piggybacks on the existing
deep scan — Plex/Jellyfin/Navidrome all return file size in their
track API responses, so we read it during the deep scan and store
it on the tracks row. Aggregation is then a single SQL query — no
filesystem walk, no extra I/O during the scan, no separate stat
job. SoulSync standalone gets size from os.path.getsize at insert
time (different code path; the file is local when we write the row).
Schema (`database/music_database.py`):
- New `file_size INTEGER` column on `tracks`. Migration uses the
established `try SELECT, except ALTER TABLE ADD COLUMN` pattern.
Idempotent; safe on existing installs. NULL on legacy rows so
they don't contribute to totals until next deep scan refreshes.
- Added the column to the canonical CREATE TABLE so fresh installs
get it without going through the migration path.
Track-object plumbing:
- `core/jellyfin_client.py` — JellyfinTrack reads MediaSources[0].Size
alongside existing Bitrate read. None when 0 / missing.
- `core/navidrome_client.py` — NavidromeTrack reads `size` from
the Subsonic song object (int coercion + None on parse fail).
- `core/soulsync_client.py` — SoulSyncTrack does os.path.getsize
(only "server" where size has to come from disk).
- Plex needs no client-side change: track.media[0].parts[0].size
is read directly inside insert_or_update_media_track.
Persistence — TWO separate insert paths:
(a) `database/music_database.py:insert_or_update_media_track` —
Plex/Jellyfin/Navidrome flows. Reads file_size from Plex's
MediaPart OR `track_obj.file_size` wrapper attribute (defensive
Plex-attr-not-present check + > 0 type guard).
INSERT writes the new column.
UPDATE uses COALESCE(?, file_size) so a None from the server
on a re-sync (rare Jellyfin Size omission) doesn't blank an
existing value. Pinned via test.
(b) `core/imports/side_effects.py:record_soulsync_library_entry` —
SoulSync standalone flow. Completely separate code path: the
standalone deep scan moves files to staging for auto-import
rather than calling insert_or_update_media_track. After the
auto-import processes them, side_effects writes the tracks row
directly. Reads file_size via os.path.getsize(final_path) at
insert time (file is local) and includes it in the INSERT
column list. SoulSync only does INSERT-if-not-exists (no
UPDATE path), so no COALESCE concern.
Aggregator (`database/music_database.py:get_library_disk_usage`):
- SELECT COALESCE(SUM(file_size), 0), COUNT(file_size),
COUNT(*) - COUNT(file_size) for the totals.
- Per-format breakdown done in Python via os.path.splitext over
(file_path, file_size) rows — sidesteps SQLite's first-vs-last-dot
ambiguity for paths like /music/Kendrick/M.A.A.D City/01.flac.
- Defensive: skips empty paths, paths without extension, and
implausibly long extensions (>6 chars). Returns the full
empty-shape dict (NOT a partial / undefined) when the column
doesn't exist or queries fail, so the UI's `if (!data.has_data)`
branch handles fresh installs cleanly.
API + UI:
- `core/stats/queries.py` — thin pass-through get_library_disk_usage
matching the existing query-helper convention.
- `web_server.py` — new /api/stats/library-disk-usage endpoint
mirroring the /api/stats/db-storage pattern.
- `webui/index.html` — new card in System Statistics above the
Database Storage card.
- `webui/static/stats-automations.js` — _loadLibraryDiskUsage +
_renderLibraryDiskUsage. Empty state: "Run a Deep Scan to
populate (X tracks pending)". Partial: "X measured (+Y pending)".
Full: total + format bars proportional to the largest format.
- `webui/static/style.css` — .stats-disk-* styled to match the
Database Storage card.
Backward compatibility:
- Migration is additive; existing rows get NULL file_size; the
empty-shape return from the aggregator means the UI renders
cleanly without errors before any deep scan runs.
- Old installs upgrading will see "Run a Deep Scan to populate
(N tracks pending)". Running their next deep scan fills sizes —
the existing scan flow doesn't need any changes, just consumes
the new track-wrapper attribute.
Tests:
- `tests/test_library_disk_usage.py` — 13 cases covering schema
migration, NULL defaults on legacy inserts, fresh-install empty
shape, summing with mixed NULL/known sizes, per-format breakdown,
mixed-case extensions, paths with album-name dots, missing
extensions, empty file_path, implausibly long extensions,
JellyfinTrack.file_size persistence via insert_or_update_media_track,
COALESCE preservation on null re-sync.
- `tests/imports/test_import_side_effects.py` — extended the
existing record_soulsync_library_entry test to assert
track_row['file_size'] == os.path.getsize(final_path), pinning
the SoulSync-standalone path. Test fixture's tracks schema also
updated to include the file_size column.
Verified: full suite 1813 pass (13 new, 1 existing-test extension),
ruff clean, smoke test populating + reading the column round-trips
correctly.

User report: every downloaded track in an album came out with
``replaygain_track_gain: +52.00 dB`` regardless of actual loudness.
Root cause: the parser at ``core/replaygain.py:79`` used
``re.search('I:\s+...')`` which returns the FIRST match. ffmpeg's
ebur128 filter emits ``I:`` per measurement window (running partial
integrated loudness) AND in a final Summary block. The first
per-window reading is at t=0.5s — almost always ~-70 LUFS because
nearly every track starts with silence / encoder padding. So:
gain = RG2_reference - lufs = -18 - (-70) = +52.00 dB
…on EVERY track. Same regex pattern, same first per-window match,
same +52 dB written to every file's REPLAYGAIN_TRACK_GAIN tag.
Verified by running ffmpeg ebur128 against a real generated FLAC
and inspecting the stderr output — first per-window line at t=0.5s
shows ``I: -70.0 LUFS`` (silent intro), and the Summary block at
the end shows the real integrated value (e.g. ``I: -27.8 LUFS``
for the test sine wave). Old code captured the -70.0 reading.
Fix: anchor LUFS parsing to the ``Summary:`` block via
``stderr.rfind('Summary:')``. The Summary block is always emitted
last and contains the authoritative final integrated loudness.
Peak parsing already worked correctly (per-window output uses
``TPK:``/``FTPK:`` labels; only the Summary uses ``Peak:``), but
applied the same Summary anchor for consistency.
Defensive fallback: if no Summary block is present (truncated
output / unusual ffmpeg version), use the LAST per-window reading
instead of the first. Still better than the buggy first-window
behavior.
Smoke verified end-to-end: a freshly-generated FLAC of a -24 dBFS
sine wave now reports LUFS=-27.80, gain=+9.80 dB (correct, was
+52.00 before fix).
Tests: ``tests/test_replaygain_summary_parse.py`` — 7 cases pinning
the parser behavior with realistic ffmpeg ebur128 stderr samples:
- Summary value parsed correctly even when first per-window is -70
- Resulting gain is realistic (NOT +52)
- Two tracks with same first per-window but different summaries get
different LUFS (regression assertion for "all tracks same gain")
- Per-window reading higher than Summary doesn't leak through
- Fallback to last per-window when Summary absent
- Clean RuntimeError raised when no LUFS values anywhere
- Peak still correctly anchored to Summary
Verified: full suite 1800 pass (7 new), ruff clean.

User caught downloading Kendrick Mr. Morale: three tracks (Rich
Interlude, Savior Interlude, Savior) showed ✅ Completed in the modal
but were missing on disk. Log forensics revealed two layered bugs.
Bug 1 — Verification wrapper assumed success on quarantined files
(`core/imports/pipeline.py`):
The outer `post_process_matched_download_with_verification` had a
fallback at the "no `_final_processed_path` in context" branch that
marked the task completed and notified `success=True`. The inner
post-processor sets `_final_processed_path` only when the file
actually reaches its destination. Integrity-rejected files
(`_integrity_failure_msg` set) and race-guard-failed files
(`_race_guard_failed` set) get quarantined or skipped without ever
setting `_final_processed_path`, so they fell straight into the
"assume success" branch.
Confirmed in user's log:
No _final_processed_path in context for task d5b88b84-... —
cannot verify, assuming success
That line fired for the same task right after the integrity check
quarantined the source file. Result: ✅ Completed in UI, file in
quarantine, never delivered.
Fix: explicit checks for `_integrity_failure_msg` and
`_race_guard_failed` markers BEFORE the assume-success fallback.
Either marker set → task status='failed' with descriptive
error_message + `_notify_download_completed(success=False)`. The
pre-existing assume-success behavior preserved when no failure
markers are set (some legitimate flows complete without setting
`_final_processed_path`).
Bug 2 — AcoustID skip-logic too lenient
(`core/acoustid_verification.py`):
The "language/script" exemption was:
if best_score >= 0.95 and (title_sim >= 0.55 or
artist_sim >= ARTIST_MATCH_THRESHOLD):
The OR-clause fired for English-vs-English titles by the same artist
that share NO actual content. Confirmed in user's log: requested
"Rich (Interlude)" by Kendrick Lamar, AcoustID identified the audio
as "R.O.T.C. (interlude)" by Kendrick Lamar (a totally different
song from his 2010 mixtape) — same artist scored ≥ARTIST threshold,
shared word "interlude" pushed title_sim above 0.55, skip fired.
Verification returned SKIP instead of FAIL, the wrong file was
accepted as the answer for three different track requests.
Fix: skip now requires positive evidence the mismatch is a real
language/script case:
(a) Non-ASCII chars present in either title AND artist matches strongly
→ real transliteration case (kanji ↔ romaji etc)
(b) BOTH title_sim >= 0.80 AND artist_sim >= ARTIST threshold
→ minor punctuation/casing differences
English-vs-English with very different titles by the same artist no
longer skipped — verification correctly returns FAIL, the wrong file
gets quarantined, the new wrapper logic above marks the task failed.
Tests:
- `tests/test_integrity_failure_marks_task_failed.py` — 4 cases
pinning the wrapper-level state machine: integrity marker → failed,
race-guard marker → failed, no markers → still assumes success
(legacy path preserved), integrity-failure-takes-priority over
missing-final-path fallback.
- `tests/test_acoustid_skip_logic.py` — 7 cases pinning the skip
exemption: user's R.O.T.C-vs-Rich case → FAIL (regression test),
Savior-vs-R.O.T.C → FAIL (same bug surface), Japanese kanji →
romaji → SKIP (real language case still works), MAAD vs M.A.A.D →
PASS or SKIP (punctuation tolerance), low fingerprint score →
never skipped, high score but artist mismatch → no longer skipped,
Crown vs Crown of Thorns → no longer skipped.
Verified: full suite 1793 pass (11 new), ruff clean.

Discord report (Samuel [KC]): tracks of the same album sometimes carry
different MUSICBRAINZ_ALBUMID tags, which causes Navidrome (and other
media servers grouping by album MBID) to split the album into multiple
entries. Two-part fix — one for existing libraries, one for the root
cause that lets new imports drift.
Part 1 — Detector + fix action (catches existing dissenters):
`core/repair_jobs/mbid_mismatch_detector.py`:
- New helpers: `_read_album_mbid_from_file` and
`_write_album_mbid_to_file` use the Picard-standard tag conventions
(`TXXX:MusicBrainz Album Id` for MP3, `MUSICBRAINZ_ALBUMID` for
FLAC/OGG, `----:com.apple.iTunes:MusicBrainz Album Id` for MP4).
- New scan phase `_scan_album_mbid_consistency` runs after the
existing track-MBID scan: groups tracks by DB `album_id`, reads
each track's embedded album MBID, finds the consensus
(most-common) MBID via `Counter`, flags dissenters. Tracks without
an album MBID at all are skipped (they don't break Navidrome —
only an explicit MBID disagreement does). Albums where MBIDs are
perfectly tied (no clear consensus) are skipped too — surface as
a manual decision instead of fixing toward a 1/N tie.
- New finding type `album_mbid_mismatch` carries `consensus_mbid`,
`wrong_mbid`, `consensus_count`, `total_tracks_with_mbid`, and a
human-readable reason string.
`core/repair_worker.py`:
- Added `'album_mbid_mismatch': self._fix_album_mbid_mismatch` to the
fix dispatch dict and to the `fixable_types` tuple so auto-fix +
bulk-fix paths pick it up.
- New `_fix_album_mbid_mismatch` method reads `consensus_mbid` from
finding details, resolves the dissenter's file path via the shared
library resolver, calls `_write_album_mbid_to_file` to rewrite the
tag in place. Doesn't touch the album's other tracks (they're
already in agreement).
Part 2 — Root cause fix (prevents new SoulSync imports from drifting):
The original in-memory `mb_release_cache` in `core/metadata/source.py`
maps `(normalized_album, artist) -> release_mbid` so per-track
enrichment of the same album hits the cache and writes the same
MUSICBRAINZ_ALBUMID to every track. That cache is bounded (4096
entries) and in-process — so cache eviction (when other albums are
processed in between) and server restart can BOTH cause
inconsistency. Per-track album-name variation (e.g. some tracks
tagged `"Album"`, others tagged `"Album (Deluxe)"`) and per-track
artist variation (features) make it worse.
`core/metadata/album_mbid_cache.py` (new module):
- DB-backed `lookup(normalized_album, artist) -> release_mbid` and
`record(...)` functions. Same key shape as the in-memory cache.
- Strict additive design: every public function is wrapped in
try/except and degrades to None / no-op on ANY database error.
The existing in-memory cache + MusicBrainz lookup remains the
authoritative fallback. If this module breaks, downloads continue
exactly as they would today.
`database/music_database.py`:
- New `mb_album_release_cache` table with composite primary key
`(normalized_album_key, artist_key)`. Reverse-lookup index on
`release_mbid` for future debug tooling. Created via the existing
`CREATE TABLE IF NOT EXISTS` migration pattern — idempotent, no
schema version bump needed.
`core/metadata/source.py`:
- Surgical change inside the existing `embed_source_ids`
in-memory-cache-miss branch: BEFORE calling MusicBrainz, consult
the persistent cache. If a previous SoulSync run already resolved
this album's release MBID, reuse it. After a successful MB lookup,
store in BOTH caches. Both calls wrapped in defensive try/except
so any failure falls through to existing logic.
Tests:
- `tests/metadata/test_album_mbid_cache.py` — 16 cache tests:
round-trip, idempotent re-record, overwrite semantics, clear_all,
album+artist independence (no Greatest Hits collisions),
defensive None-on-empty-input, graceful degradation when the DB
is unavailable / connection raises / commit fails, schema sanity
(table + index exist after init).
- `tests/test_album_mbid_consistency.py` — 13 detector tests:
tag read/write round-trip on real FLAC files, Picard-standard tag
descriptors, defensive paths (unreadable file, empty input),
detector behavior (agreement → no flags, lone dissenter → flag,
ties → no flag, single-track albums → skipped, no-MBID tracks →
skipped, unresolvable file paths → skipped).
- `tests/metadata/test_metadata_enrichment.py` — added autouse
fixture monkeypatching the persistent cache to no-op for tests in
this file. The existing tests pin per-call MB counts and
in-memory cache state; without the fixture, persistent rows from
earlier tests would bypass the MB call. Persistent layer has its
own dedicated tests.
Verified: 1782 tests pass (29 new), ruff clean, smoke test confirms
end-to-end cache round-trip works.

Investigation surfaced that Lidarr was wired into the orchestrator but
the actual download flow had blockers:
1. **Wrong file misfiled.** Lidarr grabs whole albums; SoulSync's
matched-context post-processing wants the SPECIFIC track the user
requested. Old code copied every track in the album and reported
`imported_files[0]` as `file_path` — almost always pointing to
track 1, not the user's actual track. Post-processing then tagged
track 1 with the requested track's metadata. Misfiling on every
real download.
Fix: parse the wanted track title out of the dispatch display name
(which `_search_sync` already builds as
`f"{artist} - {album} - {track_title}"`), look it up against
Lidarr's `track` API, resolve the matching `trackFileId` to a path,
and copy ONLY that file. Punctuation-tolerant fuzzy match handles
the common "m.A.A.d city" vs "maad city" case. Album-level
dispatches (no track in the display) preserve the old first-file
fallback so existing album-grab UX is unchanged.
2. **Hardcoded `metadataProfileId=1`.** Required by Lidarr's
artist-add API. On installs where the user deleted/recreated
metadata profiles, that id no longer exists and the call fails
with HTTP 400 — which silently breaks every download flow that
needs to add an artist. Real-world Lidarr installs do this all
the time.
Fix: `_get_metadata_profile_id()` calls Lidarr's `metadataprofile`
API and returns the first available id. Falls back to 1 only when
the API call fails entirely (preserves previous behavior so this
change can't make things worse).
3. **Polling never broke the outer loop on completion.** The inner
`for item in queue['records']` had `break` statements at status
transitions, but those only escaped the queue iteration — the
outer `for poll in range(max_polls)` kept spinning until the
600-poll timeout even after the album was clearly imported.
`for/else` semantics didn't apply because completion was detected
inside the inner loop, not by it running to exhaustion.
Fix: replaced with an explicit `download_complete` flag set when
`album/{id}` reports `trackFileCount > 0` (the authoritative
completion signal — works even when the queue record disappeared
between polls). Outer loop breaks immediately once the flag flips.
Helper functions added: `_extract_wanted_track_title` (staticmethod,
splits the display name; >=3 parts → track dispatch, 2 parts → album
dispatch), `_normalize_for_match` (lowercase + strip punctuation +
collapse whitespace for fuzzy compare), `_title_similarity` (cheap
score: equal=1.0, substring=0.85, token-overlap-ratio otherwise),
`_pick_track_file_for_wanted` (orchestrates the API calls).
Settings tooltip updated to be honest about Lidarr's natural shape:
album-grabber, no-op for playlist sync, hybrid mode falls through to
other sources for track searches. Sets correct expectations.
Tests: `tests/test_lidarr_download_client.py` — 21 isolated tests
covering pure helpers (title extraction, normalization, similarity)
and the file-picker integration paths (matching path, punctuation
tolerance, below-threshold fallback, missing trackFileId, missing
file on disk, API failures, malformed responses). No live Lidarr
needed — `_api_get` mocked at the client boundary.
Isolation: ONLY touches `core/lidarr_download_client.py`, the Lidarr
settings tooltip in `webui/index.html`, the Lidarr WHATS_NEW entry
in `webui/static/helper.js`, and the new test file. No changes to
the orchestrator, other download clients, the import pipeline,
side_effects, web_server.py, settings.js, or any shared validation /
monitor / task_worker code. Other download sources are not affected
in any way.
Verified: 1753 tests pass (21 new), ruff clean.
User report: switched download source to SoundCloud and noticed:
1. Download progress % stays at 0 until "suddenly done" — no live progress
2. Sidebar status indicator next to "SoundCloud" label is red
3. Dashboard service status card still shows "Soulseek" as the source name
Fix 1 — Live progress for HLS-segmented SoundCloud downloads
(`core/soundcloud_client.py`):
- yt-dlp's `total_bytes` / `total_bytes_estimate` for HLS describes the
CURRENT FRAGMENT, not the whole download. So the byte-based
percentage stayed near 0 the entire time — until 'finished' fired.
- Added `_update_download_progress_fragmented` which uses
`fragment_index` / `fragment_count` (which yt-dlp DOES populate
accurately for HLS) to compute a meaningful percentage. Total size
is extrapolated from per-fragment average for the bytes/remaining
display. Time-remaining estimate uses elapsed/index seconds-per-
fragment.
- The progress hook prefers fragment progress when both fragment_index
and fragment_count are present; falls back to byte-based for
non-fragmented (progressive MP3) downloads. Five new unit tests pin
the fragment-progress math, the 99.9% cap, and the defensive
zero-index / unknown-id paths.
Fix 2 — Sidebar status indicator stays green for SoundCloud mode
(`web_server.py`):
- The `/api/status` route's `serverless_sources` tuple decides whether
to even probe slskd. SoundCloud (and Lidarr) were missing — so when
the active source was SoundCloud, the route fell through to "test
slskd, mark not-relevant", which set `connected: False` and turned
the sidebar dot red even though SoundCloud was working.
- Added `'soundcloud'` and `'lidarr'` to the tuple. Both are
serverless from slskd's perspective, so the dot now stays green
whenever they're the active source.
Fix 3 — Dashboard service card title shows the active source
(`webui/static/shared-helpers.js`):
- The dashboard's "Download Source" card has its own
`sourceNames` map at line 3351 (separate from the sidebar map I
already updated at 3396). Missed it during the integration PR.
- Added `'lidarr'` and `'soundcloud'` so the card title now reads
"SoundCloud" / "Lidarr" instead of falling back to "Soulseek".
Bonus — Dashboard "Test Connection" button works for SoundCloud
(`core/connection_test.py`):
- The dashboard's Test Connection button on the download-source card
sends `service` based on the active source — so for SoundCloud it
was sending `service='soundcloud'`. `run_service_test` had no
branch for it, so it fell through to "Unknown service." and the
button always failed.
- Added a `soundcloud` branch that mirrors `/api/soundcloud/status`
behavior: confirms yt-dlp is installed, runs a real cheap probe,
returns a meaningful pass/fail. (HiFi has the same gap but no
user reported it; out of scope for this fix.)
Verified:
- 41 unit tests pass (5 new fragment-progress tests added)
- Full suite 1732 passed
- Ruff clean
Plug the previously-built SoundcloudClient (PR #478, the build-and-verify
phase) into every place a download source needs to appear. Follows the
same wiring contract as Tidal/Qobuz/HiFi/Deezer/Lidarr — orchestrator
routing, hybrid-mode picker, search dispatch, queue/cancel/clear,
provenance + library history, sidebar source label, settings UI all
work plug-and-play.
Backend wiring:
- `core/download_orchestrator.py` — import SoundcloudClient, _safe_init
it at startup, add to _client() lookup, get_source_status(),
check_connection's sources_to_check default, search source_names map,
search_and_download_best _streaming_sources tuple, download
source_map + source_names, and every iteration loop in
reload_settings download-path-update / get_all_downloads /
get_download_status / cancel_download (route + iterate) /
clear_all_completed_downloads / cancel_all_downloads.
- `core/downloads/monitor.py` — added SoundCloud to the per-client
loop that fetches active downloads outside the orchestrator (uses
getattr fallback for older soulseek_client snapshots).
- `core/downloads/task_worker.py` — added SoundCloud (and Lidarr,
which was missing too — bonus fix) to source_clients dict for hybrid
fallback dispatch.
- `core/downloads/validation.py` — added 'soundcloud' to
_streaming_sources so SoundCloud results go through the matching
engine validation path instead of the Soulseek quality-filter path.
- `core/imports/side_effects.py` — three call sites: source_map for
download_source label written to library_history, streaming-source
guard for the `||`-encoded stream_id parsing, and source_service
map for provenance recording. All three now include 'soundcloud'.
- `web_server.py` — five streaming-source detection tuples updated.
New `/api/soundcloud/status` endpoint returns
{available, configured, reachable} mirroring the Deezer/HiFi
status-endpoint pattern; reachability runs a real cheap yt-dlp
search so the settings Test Connection button gives a meaningful
pass/fail signal.
- `config/settings.py` — added empty `soundcloud_download` defaults
block so future tier-2 OAuth (SoundCloud Go+ session) doesn't have
to migrate existing configs.
Frontend:
- `webui/index.html` — new `<option value="soundcloud">` in the
download-source-mode dropdown, SoundCloud added to both hidden
legacy hybrid-source selects, new settings container with info
text + Test Connection button.
- `webui/static/settings.js` — HYBRID_SOURCES entry (with the
SoundCloud cloud SVG icon), _hybridSourceEnabled default,
updateDownloadSourceUI container display, allSources for legacy
hybrid picker, testSoundcloudConnection function (hits the new
status endpoint, color-codes the result), saveSettings
soundcloud_download empty block.
- `webui/static/shared-helpers.js` — sidebar source-name map
includes SoundCloud + Lidarr (Lidarr was also missing, bonus fix).
- `webui/static/helper.js` — WHATS_NEW entry under '2.4.2' dev cycle
describing the user-visible change in the chill terse voice.
Tests:
- `tests/test_download_orchestrator_soundcloud.py` — 14 integration
tests verifying the wiring: client constructed at startup, _client
lookup resolves 'soundcloud', get_source_status includes it,
download dispatcher routes username='soundcloud' to the SoundCloud
client (and unknown usernames still fall back to Soulseek), hybrid
search iterates SoundCloud when in order and skips it cleanly when
unconfigured, get_all_downloads / get_download_status / cancel /
clear walk SoundCloud, soundcloud-only mode dispatches only to
SoundCloud, _streaming_sources tuple in validation includes
'soundcloud'.
- `tests/downloads/test_download_orchestrator.py` — added
`soundcloud` to the test fixture's _build_orchestrator helper so
the new orchestrator attribute doesn't AttributeError in pre-
existing tests that bypass __init__.
Verified:
- Full suite green (1728 passed, 2 deselected for soundcloud_live)
- Ruff clean
- Live SoundCloud-only mode search returns 25 SoundCloud tracks for
"kendrick lamar luther" in <2s, returning properly-shaped
TrackResult objects with username='soundcloud' and dispatch-key
filename ready for the download path.
Out of scope (intentional deferrals):
- SoundCloud Go+ OAuth tier (256 kbps AAC) — anonymous-only for now.
Adding auth later is a settings-page extension, no orchestrator
changes needed.
- Album/playlist support — SoundCloud has playlists but they don't
map to the album model the rest of SoulSync expects. Singles only.
Discord request (Toasti): some tracks (DJ mixes, sets, removed Spotify
content) only live on SoundCloud. Add SoundCloud as an option for the
existing multi-source download dispatch.
This commit only ships the client + tests. Integration into the search
dispatch / settings UI / web_server.py routes is intentionally deferred
to a follow-up PR — the user-requested workflow is build-and-verify
in isolation first, then wire up.
`core/soundcloud_client.py`:
- SoundcloudClient class mirrors the public surface of every other
download client (TidalDownloadClient, QobuzClient, HiFiClient,
DeezerDownloadClient): __init__(download_path), set_shutdown_check,
is_available / is_configured / is_authenticated, async check_connection,
async search returning (List[TrackResult], List[AlbumResult]),
async download returning a download_id, _download_thread_worker /
_download_sync / _update_download_progress, async get_all_downloads /
get_download_status / cancel_download / clear_all_completed_downloads.
- Underlying lib: yt-dlp (already in requirements.txt as 2026.3.17).
- Anonymous-only — public SoundCloud tracks at the cap quality (typically
128 kbps MP3, occasionally 256 kbps AAC depending on the upload).
No FLAC ever; SoundCloud doesn't expose lossless. OAuth tier for
SoundCloud Go+ is documented in the module header as a future tier.
- Returns standard TrackResult / DownloadStatus dataclasses from
core.soulseek_client so downstream matching/post-processing stays
source-agnostic.
- Filename dispatch key encodes track_id + permalink_url + display_name
so the download worker has everything without re-querying.
- Heuristic "Artist - Title" parser handles SoundCloud uploaders'
typical title format; falls back to uploader handle as artist when
the title doesn't have a separator.
- Defensive: search returns empty on bad input, missing yt-dlp, or any
raised exception. Download sync rejects files under 100KB (preview
snippets / broken responses) and cleans them up.
- Cooperative cancellation via shutdown_check inside yt-dlp's
progress_hooks. Cancelled state survives the download thread's
terminal-state assignment.
`tests/test_soundcloud_client.py`:
- 37 unit tests with yt-dlp stubbed: search shape correctness, the
artist/title heuristic, the dispatch-key roundtrip, the download
state machine (success / failure / shutdown / Cancelled-state
preservation), the progress emitter (progress capping, time
remaining), defensive paths (missing yt-dlp, raising yt-dlp,
malformed entries, empty entries), and the cancel/clear ledger
operations.
- 2 live integration tests gated behind `-m soundcloud_live` so CI
doesn't run them by default. Run locally with:
python -m pytest tests/test_soundcloud_client.py -m soundcloud_live -v
- All 37 unit tests pass; both live tests pass against real SoundCloud.
- Verified end-to-end with a real album download (Kendrick GNX, 12/12
tracks, 4-7 MB each, completed under 60s per track).
`pyproject.toml`:
- Register the `soundcloud_live` pytest marker so the unknown-mark
warning is suppressed and the live tests can be cleanly gated.
Not changed: web_server.py, settings UI, search dispatch, matching
engine, WHATS_NEW. Integration is the next PR.
GitHub issue #476 (gabistek, Docker on Arch host): "Auto-Fill" / "Fix
Selected" on the Album Completeness findings page returned
"Could not determine album folder from existing tracks" for every album.
Reproduces on any setup where the media-server library lives outside the
SoulSync transfer/download folders — Docker is the headline case but
native installs that point Plex at a NAS via SMB hit it too.
Root cause: `core/repair_worker.py:_resolve_file_path` only probed the
transfer + download folders. Docker users have their Plex/Jellyfin
library bind-mounted at /music (or similar) — neither configured in
SoulSync. Every existing track got silently treated as missing, so
`album_folder` stayed None and the fix workflow bailed.
The same incomplete logic was duplicated four more times in the
repair_jobs/ modules, all with the same bug. Album Completeness was
just the most user-visible — the same setups were also producing false
"missing file" findings from Dead File Cleaner, silent skips in
MBID Mismatch Detector, etc.
The web server already had the correct logic at
`web_server.py:_resolve_library_file_path` (probes transfer + download
+ Plex-reported library locations + user-configured library.music_paths).
The repair workers had never been updated to match.
Fix:
- New `core/library/path_resolver.py` extracts the union logic into a
single shared function `resolve_library_file_path()`. Probes (in
order, deduped): explicit transfer/download kwargs, config-derived
soulseek.transfer_path/download_path, Plex-reported library
locations (when a plex_client is passed), user-configured
library.music_paths. Each defensive: malformed config or a flaky
Plex client degrades to the dirs that did succeed.
- `core/repair_worker.py:_resolve_file_path` becomes a delegating
wrapper preserving the legacy signature, with a new `config_manager`
kwarg. All 15 in-tree call sites updated to thread
`self._config_manager` through.
- `core/repair_jobs/dead_file_cleaner.py`,
`mbid_mismatch_detector.py`, and `lossy_converter.py` get the same
treatment: duplicate function replaced with a thin wrapper, call
sites pass `context.config_manager`.
- `core/repair_jobs/acoustid_scanner.py` and
`unknown_artist_fixer.py` (which used to import from repair_worker)
now call the shared resolver directly with `context.config_manager`.
Side benefit: every other repair job (Dead File Cleaner, MBID
Mismatch Detector, Lossy Converter, AcoustID Scanner, Unknown Artist
Fixer) also stops missing files in the media-server library mount.
Single fix unblocks five user-visible features.
Tests: `tests/library/test_path_resolver.py` — 20 cases covering all
four base-dir sources, suffix-walk algorithm, dedup, defensive paths
(None plex client, malformed config entries, raising config_manager.get,
broken plex attribute access), Docker path translation. Full suite
1677 passed locally.
WHATS_NEW entry under '2.4.2' dev cycle.
Discord report (fresh.dumbledore [VRN]): slskd sometimes ships broken files
(truncated transfers, corrupt FLAC, wrong file substituted on filename match).
They flowed through post-processing and only surfaced later — Plex/Jellyfin
scan failures, dead-air playback, duplicate detector tripping over the wrong
length. By that point the file was already tagged, copied, mirrored to the
media server, and recorded in provenance.
New module `core/imports/file_integrity.py`:
- `check_audio_integrity(path, expected_duration_ms=None) -> IntegrityResult`
- Three tiered checks, cheapest to most expensive:
1. File size sanity (catches 0-byte stubs and stub transfers)
2. Mutagen parse (catches header damage, wrong-format-with-right-extension)
3. Duration agreement vs. metadata source's expected length, ±3s tolerance
(5s for tracks over 10 minutes — long tracks naturally drift more)
- Returns IntegrityResult with `ok`, human-readable `reason`, and per-check
`checks` dict for debugging
- Never raises; pathological inputs return ok=False with explanation
Pipeline integration in `core/imports/pipeline.py:post_process_matched_download`:
- Hooks between the existing file-stability wait and AcoustID verification
- On failure: quarantine via existing `move_to_quarantine` helper, mark task
failed with descriptive error, clear matched-context, fire
`on_download_completed(success=False)` so the slot is released for retry
- Mirrors the existing AcoustID-failure path so retry behavior stays consistent
- Wrapped in try/except so an unexpected failure inside the check itself
cannot block downloads — logs and continues
This is intentionally tier 1: universal across formats, no external deps.
A future tier could verify FLAC STREAMINFO MD5 by decoding audio (needs
flac binary or libflac wrapper) — skipped for now since tier 1 catches the
dominant Discord-reported cases (truncated, 0-byte, wrong file).
Tests:
- `tests/imports/test_file_integrity.py` — 14 cases covering all three check
tiers, edge cases (zero/negative expected duration, long-track wider
tolerance, caller tolerance override), and the mutagen-unavailable
degradation path
- `tests/imports/test_import_pipeline.py` — two existing tests use 5-byte
fixture files that the new check would reject; they monkeypatch the
integrity check since they're testing plumbing (notification +
metadata_runtime forwarding), not integrity behavior
WHATS_NEW entry under '2.4.2' dev cycle.
The 'Live Per-Track Progress' work shipped a backend in-progress row + top-of-tab
progress text but the history cards themselves stayed visually stale during
processing — lowercase "processing" badge, neutral styling, no per-track hint.
Smoke-testing also surfaced two latent identification bugs that prevented
multi-disc rips with features (Kendrick GKMC Deluxe) from importing at all.
Card-level live progress (`webui/static/stats-automations.js`):
- Cache `/api/auto-import/status` response in `_autoImportLastStatus`; poller
awaits status before re-rendering results so the card has the live data.
- Add 'processing' entries to statusLabels / statusIcons / statusClass.
- When card folder_name matches `current_folder`, swap the meta line to
`track N/M: <track name>` and tag the matching row in the expanded list
as `auto-import-track-row-active`; prior rows tag as `-row-done`.
Card styling (`webui/static/style.css`):
- `.auto-import-processing` blue left border, `.auto-import-badge-processing`
pulse animation, active/done track-row classes.
Multi-disc enumeration (`core/auto_import_worker.py:_scan_directory`):
- Old code skipped disc folders during recursion AND only attached them to a
parent that had its own loose audio. A folder containing only `Disc 1/`,
`Disc 2/` was invisible. Now: when a directory has only disc subdirs and no
loose audio, treat that directory itself as the album candidate. Disc folders
still skipped when standing alone.
- Add `FolderCandidate.is_staging_root` flag (set when the staging dir itself
becomes the candidate via this path) so identification can refuse to use the
meaningless folder name.
Tag identification (`core/auto_import_worker.py:_identify_from_tags`):
- Per-track `artist` tag fragmented consensus on albums with features
("Kendrick Lamar" / "Kendrick Lamar, Drake" / "Kendrick Lamar, Dr. Dre"
produced 3 separate `(album, artist)` keys for one album). Now group by
album first, then pick the most-common artist within that album group.
- `_read_file_tags` now prefers `albumartist` over `artist` for album-level
identity; falls back to `artist` for files without albumartist.
- Add INFO-level log when tag identification rejects, showing top albums and
their counts so the user can diagnose multi-disc / tagging issues.
Folder-name false-match guard (`core/auto_import_worker.py:_identify_folder`):
- When `is_staging_root` is set, skip the folder-name strategy entirely. Logs
the skip and falls through to AcoustID. Without this, dropping disc folders
directly into staging caused the scanner to search the metadata source for
the literal name "Staging", which false-matched against random albums (e.g.
"Stamina, Dinos" — a French rap album — at 13% confidence).
What's New entries added under 2.4.2 dev cycle.
User reported (Mushy / generally) that dropping an album into the
staging folder left the auto-import history blank for the entire
processing window — sometimes 5+ minutes for a full album. Pre-
existing UX gap, not caused by the recent context-builder refactor.
Two root causes:
1. ``_record_result`` only fired AFTER ``_process_matches`` returned.
For a 14-track album with ~30s/track post-processing, that meant
~7 minutes of zero rows in auto_import_history → nothing for
``/api/auto-import/results`` to return → empty UI.
2. ``_current_status`` only ever transitioned between 'idle' and
'scanning' — never 'processing'. ``get_status()`` had no per-
track index/name fields, so the UI had no way to render
"Processing track 3/14: Mine" even if it wanted to.
Fix:
- New ``_record_in_progress`` inserts a status='processing' row
up-front (before the per-track loop starts) so the UI sees the
import the moment it begins. Returns the row id.
- New ``_finalize_result`` updates that same row with the final
outcome (completed/failed) when processing finishes. One row per
album, not per track — keeps the history list clean.
- Both share ``_serialize_match_data`` (extracted from the original
``_record_result``) so the in-progress row carries the same match
payload shape the existing review UI already understands.
- ``_process_matches`` updates ``_current_track_index``,
``_current_track_total``, and ``_current_track_name`` BEFORE each
per-track callback fires, so a polling UI sees consistent
"processing N/M: <name>" snapshots.
- ``_scan_cycle`` flips ``_current_status`` to 'processing' before
the per-album loop, resets it + the per-track fields after.
Defensive ``finally`` clears progress even if the inner code path
raised.
- ``get_status()`` exposes the new fields so the UI's existing
/api/auto-import/status polling picks them up.
- Frontend (stats-automations.js): renders the new
``current_status='processing'`` state with track index/total/name
in the existing progress bar element. New 'processing' status
class for styling parity with 'scanning'.
8 regression tests in tests/imports/test_auto_import_live_progress.py:
- get_status surfaces the new fields with sane defaults
- track_index advances 1, 2, 3 during a 3-track loop
- track_total set BEFORE the first callback fires (no '1/0' flicker)
- _record_in_progress writes status='processing' with no
processed_at
- _finalize_result updates the same row to completed +
processed_at, no second insert
- _finalize_result with failed status leaves processed_at NULL
- _finalize_result with row_id=None is a safe no-op
- Per-track fields cleared by _scan_cycle's finally block

Smoke-testing the just-merged provenance PR against live logs revealed
the new ID-match block was silently no-opping: no [ExtID Match] /
[Provenance Match] log lines despite the code path being live. Tracing
revealed two related gaps in extract_external_ids' source detection:
1. **Underscore-prefixed key.** Deezer / Discogs / Hydrabase clients
tag normalized track dicts with ``_source`` (underscore prefix —
convention used in 8+ places across core/). The extractor only
looked for ``provider`` and ``source``, so Deezer-sourced tracks
silently returned no IDs.
2. **No provider field at all.** Spotify and iTunes raw API responses
carry ``id`` but no provider/source key of any kind. The extractor
couldn't disambiguate the native ``id``, so Spotify-primary scans
would have hit the same silent miss once the user switched primary
sources.
Two-part fix:
- ``extract_external_ids`` now recognizes ``_source`` as another
candidate provider field.
- New optional ``source_hint`` parameter lets the caller supply the
configured primary source as a fallback when the track dict has no
provider field of its own. Track-side provider field still wins
when present (defensive against a wrong hint).
Watchlist scanner now passes ``get_primary_source()`` as the hint so
both naming conventions (Deezer-style _source, Spotify-style no-tag)
get handled uniformly.
6 new regression tests cover:
- _source recognized for Deezer
- _source recognized for Hydrabase (cross-provider mapping)
- _source recognized for Discogs (no library column — verifies
graceful no-crash)
- source_hint disambiguates raw tracks for spotify/itunes/deezer
- track-side provider takes precedence over hint
- None hint defaults safely
Full pytest 1630 passed; ruff clean. After this lands and the server
restarts, watchlist scans should produce [ExtID Match] /
[Provenance Match] log lines for tracks already on disk regardless of
which metadata source the user has configured as primary.
Followup to fix/watchlist-external-id-match. The companion PR closed
the demand side — the watchlist scanner asks for tracks by external IDs
before falling back to fuzzy. But for users on Plex / Jellyfin /
Navidrome the supply side was still broken: tracks.spotify_track_id
(and the other ID columns) only got populated by the asynchronous
enrichment workers, sometimes hours after the file was actually
written. During that window the ID match fell through to fuzzy and
the bug returned.
We were already collecting every ID during post-processing — they
live in the `pp` dict in core/metadata/source.py:embed_source_ids and
get embedded into file tags. We just dropped the in-memory copy
afterwards.
This PR persists them and uses them:
- Schema migration adds spotify_track_id / itunes_track_id /
deezer_track_id / tidal_track_id / qobuz_track_id /
musicbrainz_recording_id / audiodb_id / soul_id / isrc columns +
indexes to the existing track_downloads table (already keyed by
file_path).
- core/metadata/source.py:embed_source_ids exposes pp["id_tags"] and
the resolved ISRC back to the import context as _embedded_id_tags
/ _isrc.
- core/imports/side_effects.py:record_download_provenance reads those
context fields and passes them to db.record_track_download, which
now accepts the new ID kwargs and persists them.
- New db.get_provenance_by_file_path with exact + basename-suffix
fallback (handles container mount-root differences between
download-time path and media-server-reported path).
- New db.backfill_track_external_ids_from_provenance copies IDs
from track_downloads onto a tracks row idempotently — COALESCE on
every column preserves any value the enrichment worker already
wrote (enrichment is more authoritative for late binding).
- database/music_database.py:insert_or_update_media_track (the
single insertion point used by every Plex / Jellyfin / Navidrome
sync) calls the backfill immediately after each INSERT/UPDATE.
- New core/library/track_identity.py:find_provenance_by_external_id
used as a second-tier fallback in watchlist_scanner.is_track_missing
_from_library — catches the window between download and media-server
sync. Caller checks os.path.exists on the provenance file_path
before treating it as "already in library" so a deleted file
doesn't prevent re-download.
Effect: freshly downloaded files become ID-recognizable to the
watchlist on the very next scan, no enrichment-wait window.
19 regression tests in tests/test_provenance_id_persistence.py:
- Schema migration adds expected columns + indexes
- record_track_download persists every ID kwarg
- record_track_download backward-compat (old kwargs still work)
- get_provenance_by_file_path: exact match, basename fallback for
mount-root differences, multi-record latest-wins, defensive None
- backfill: copies all IDs, preserves existing via COALESCE,
no-op when no provenance exists
- find_provenance_by_external_id: per-ID lookup, ISRC cross-bridge,
OR semantics, latest-wins on multiple matches
Out of scope: backfilling provenance for files downloaded BEFORE
this PR (their track_downloads rows don't carry the new IDs). Those
continue to wait for enrichment. Acceptable — only affects historical
files; new downloads benefit immediately.
Full pytest 1625 passed; ruff clean.
Reported case (CAL): a track already on disk got re-downloaded by the
watchlist scanner on every scan. Library DB had stale album metadata
for the file (track tagged on album "Left Alone") while the metadata
source reported it on a different album ("NPC" single). The
title+artist+album fuzzy block correctly said the album names didn't
match and declared the track missing — but the file's stable external
IDs (Spotify ID, ISRC, etc.) unambiguously identified it as the same
recording.
The earlier compilation-album fix (PR #461) handled qualifier drift
("OST" vs "Music From The Motion Picture"). This case is two
genuinely different album names referring to the same song.
Fix: provider-neutral external-ID short-circuit before the fuzzy
block in `is_track_missing_from_library`. Pulls every recognized ID
off the source track (Spotify / iTunes / Deezer / Tidal / Qobuz /
MusicBrainz / AudioDB / Hydrabase / ISRC), runs a single SELECT
against the indexed external-ID columns on the `tracks` table, and
treats any hit as "track exists in library — don't re-download".
If no IDs are available (older imports without enrichment, library
scans that didn't populate external IDs), falls through to the
existing fuzzy logic so the safety net stays intact.
New `core/library/track_identity.py` module with two helpers:
- `extract_external_ids(track)`: handles dict and object-style track
shapes, direct-field aliases (spotify_id / spotify_track_id /
SPOTIFY_TRACK_ID), and provider-disambiguated native `id` fields
(when track has `provider='deezer'` and `id='X'`, treats X as a
Deezer ID).
- `find_library_track_by_external_id(db, external_ids,
server_source)`: builds an OR of indexed column matches with
IS NOT NULL guards, optional server_source filter that also
passes legacy NULL rows, single-row LIMIT.
ISRC bridges across providers — a library track imported via Deezer
can be matched against a Spotify scan when both sides carry the
same ISRC.
43 regression tests in `tests/test_library_track_identity.py`:
- 9 ID-extraction tests for direct fields (Spotify / iTunes / Deezer /
ISRC / MBID / AudioDB / Hydrabase)
- 8 ID-extraction tests via the provider field (8 providers + source
alias + missing-provider-ignored)
- 7 mixed/defensive tests (multiple IDs, object-style, empty strings,
None track, numeric coercion)
- 8 lookup tests (per-provider + ISRC cross-bridge)
- 3 OR-semantics tests
- 4 server_source filter tests
- 2 ID-column-map sanity tests

Reported case (CAL): with lossy_copy.enabled=True,
lossy_copy.delete_original=True, and codec=mp3, every download left
both the original FLAC AND the converted MP3 in the target folder.
Users opting into a lossy-only library ended up dual-format on
every import.
Root cause: ``core/imports/file_ops.py:create_lossy_copy`` reads
``lossy_copy.codec`` and ``lossy_copy.bitrate`` from config but never
reads ``lossy_copy.delete_original``. The setting is only consulted
by the pre-move source-vanished check at
``core/imports/pipeline.py:651`` (so the pipeline knows to look for
a lossy variant when the FLAC has already moved on), but no code
path actually deletes the source after conversion.
Fix: after ffmpeg returns success and the QUALITY tag is written,
check ``lossy_copy.delete_original`` and ``os.remove`` the original
when enabled. Belt-and-suspenders:
- Same-path guard (``os.path.normpath(out_path) != os.path.normpath(final_path)``)
prevents accidentally wiping the just-converted file if a future
codec choice somehow resolves out_path to the source path.
- ``FileNotFoundError`` is treated as success (concurrent worker /
dedup cleanup got there first).
- Other ``OSError`` (permission denied, locked file) is logged but
doesn't propagate — the conversion already succeeded, the user just
has to clean up the original manually.
Failure paths skip the delete:
- ffmpeg returns non-zero → returns None, original stays
- lossy_copy.enabled=False → early return before conversion runs
- delete_original=False (default) → original stays

Note: this PR does NOT address the second bug CAL mentioned (track
re-downloaded despite already existing on disk). That symptom is
caused by stale album metadata on the user's existing files — the
library DB has the track tagged on a different album than the
metadata source reports — combined with wishlist.allow_duplicate_tracks
defaulting to True. Same class of issue partially addressed in PR
fix/watchlist-redownload-and-duplicate-detection but compilation-
album drift is the only currently-handled case. Tracking separately.
Discord-reported (Foxxify): logging in to Qobuz via the Connect
button on Settings showed "Connected: <username> (Active)" but
underneath an error said "Qobuz not authenticated...", and the
dashboard indicator stayed yellow. Saving settings or reloading the
tab didn't help.
Root cause: SoulSync runs two QobuzClient instances side by side —
one through soulseek_client.qobuz for the /api/qobuz/auth/* endpoints,
and a second owned by the enrichment worker thread for thread safety.
The login flow only updated the auth-flow instance's in-memory state
(plus persisted to config). The dashboard's "configured" check at
web_server.py:3371 reads
``qobuz_enrichment_worker.client.user_auth_token`` — the WORKER's
instance — which still believed itself unauthenticated. The
connection-test step at core/connection_test.py:370 hits the same
worker instance for the same reason.
Fix: add ``QobuzClient.reload_credentials()`` — a public, network-free
method that re-reads the saved session from config and updates the
instance's in-memory state + session headers. Call it on the
enrichment worker's client immediately after a successful
``/api/qobuz/auth/login``, ``/api/qobuz/auth/token``, or
``/api/qobuz/auth/logout`` so the two instances stay in lockstep
without waiting for the next process restart.
Unlike the existing ``_restore_session()`` this skips the network
probe — the caller has just authenticated, so the token is known
good. A small ``_sync_qobuz_credentials_to_worker()`` helper in
web_server.py wraps the call so all three endpoints share one path.
10 new regression tests cover the populate / clear / partial-config
paths plus the actual two-instance-sync scenario from the bug report.
Full pytest 1555 passed (the one pre-existing flake in
test_tidal_auth_instructions.py is order-dependent and unrelated).
- keep existing /api/image-proxy URLs from being wrapped again
- reuse the shared metadata package instead of duplicating URL logic in web_server.py
- add regression coverage for proxy passthrough and internal URL normalization
- Prefer real Spotify IDs when importing Spotify contexts
- Skip numeric fallback IDs so Deezer values do not leak into spotify_* columns
- Add regressions for import context and SoulSync library writes
- Keep the route test asserting the Spotify album link
- move Spotify status publishing onto auth, disconnect, and rate-limit transitions
- keep dashboard and debug consumers on the shared cached snapshot
- leave only the initial snapshot seed as a fallback probe
- move metadata-source and Spotify status caching out of web_server.py
- keep the public /status payload unchanged while shrinking server-side glue
- centralize invalidation and TTL handling in core/metadata/status.py
- Keep the primary metadata provider snapshot generic and move Spotify auth/rate-limit details into a separate status object.
- Update the websocket fixture and dashboard/settings consumers to read the two buckets independently.
